The Constitution should be interpreted as a living document for two reasons: 1) the Constitution was written deliberately vague enough to change over time, and 2) interpreting the Constitution as a living document has resulted in tremendous progress for our country.
1. The Constitution was designed specifically to be a living document
Critics of the living Constitution often suggest that the original intent or meaning of specific language in the Constitution should govern its legal application unless and until any constitutional amendments are passed to change it. The profound irony of this approach to constitutional interpretation, however, is that it flunks its own test; the vast weight of historical evidence suggests that the Framers of the Constitution originally intended the meaning of the Constitution to change over time.
A. The brevity of the document
At the time of its ratification in 1788, the Constitution was only 4500 words long and fit on four (admittedly large) pages. By contrast, Congressional legislation today is typically hundreds of pages long, and usually begins with a lengthy list of terms and definitions to clarify the precise meaning of its language. If the framers of the Constitution really intended the Constitution to define the precise scope of the entire federal government and the nature of core individual rights for all of perpetuity, then one would have expected the body of the constitution to be significantly larger. Of course, attempting to draft and subsequently ratify such a detailed Constitution would have proven to be an impossible task.
A specific example from the Constitution illustrates this point. In defining the Congress’ ability to “carry into execution” its enumerated powers under Article I, Sec. 8 of the Constitution, the Framers made an editorial decision to grant Congress a wide-ranging power to pass “all laws . . . necessary and proper” for that purpose. As James Madison explained in Federalist Paper # 44, this decision was made largely for the sake of convenience:
Had the convention attempted a positive enumeration of the powers necessary and proper for carrying their other powers into effect; the attempt would have involved a complete digest of laws on every subject to which the Constitution relates; accommodated too not only to the existing state of things, but to all the possible changes which futurity may produce.
This, of course, was not the framer's intent. Aside from the practical obstacles in actually drafting such a document, the Framers also wanted to keep the Constitution accessible to Americans of all backgrounds. In other words, if the Framers didn’t intend for the Constitution to be a living document, we wouldn’t have a Constitution small enough to fit in our pocket.
B. The ambiguity of its language
Even more convincing evidence for the idea of a Living Constitution, however, lies in the ambiguity of its actual language. Phrases like “general Welfare,” “due process of law,” and “free speech” are some of the most important concepts at the heart of our democracy, but their actual meaning is left completely unresolved by the naked text of the Constitution. This ambiguity was deliberate. For one thing, the delegates present at the 1787 Philadelphia Convention disagreed vigorously amongst themselves about the meaning of certain language, and keeping the document as vague as possible increased the likelihood of its ratification from the 13 states.
Less cynically, however, was the fact that the Framers simply wanted to ensure that the Constitution had the flexibility to adapt to changing circumstances. When the Constitutional Convention’s Committee of Detail met together to write the first draft of the Constitution, for example, framer Edmund Randolph advised his fellow Committee members “to insert essential principles only; lest the operations of government should be clogged by rendering those provisions permanent and unalterable, which ought to be accommodated to times and events.” 
C. The intent of its Framers
Like Randolph and Madison, other framers have endorsed the idea of a Living Constitution. In Federalist Paper # 34, Alexander Hamilton essentially criticized an "originalist understanding" of federal power:
Constitutions of civil government are not to be framed upon a calculation of existing exigencies, but upon a combination of these with the probable exigencies of ages, according to the natural and tried course of human affairs. Nothing, therefore, can be more fallacious than to infer the extent of any power, proper to be lodged in the national government, from an estimate of its immediate necessities. 
Aside from explicit quotations, we may also infer the framer’s support for a living Constitution by the circumstances surrounding their deliberations in Philadelphia. For example, if the framers really wished for their intentions to control future interpretations of the Constitution’s text, one would expect them to have kept a detailed recording of their deliberations in Philadelphia, just like Congress compiles a “legislative history” to guide future interpretation of the statutes they pass. The framers, however, declined to keep an official record of their deliberations in Philadelphia, and kept their proceedings secret from the public. This way, they ensured that future generations would not be trapped under the weight of their "original intent."
2. A Living Constitution has made us a freer and more just country
Perhaps the best argument in favor of a Living Constitution is the simple fact that it has made our country better. The legal reasoning used in the Supreme Court's landmark decision in Brown v. Board of Education demonstrates this convincingly.
After hearing oral arguments, one Justice noted that if the case had been decided then, "the vote would have been five to four in favor of the constitutionality of segregation in the public schools."  Despite unanimous disgust with the practice of segregation, five of the nine Justices didn't believe it was unconstitutional under an original intent understanding of the 14th Amendment's Equal Protection Clause, because even Northern schools were racially segregated when the Amendment was passed in 1868. One Justice's law clerk concluded that "it is impossible to conclude that the 39th Congress intended that segregation be abolished; impossible also to conclude that they foresaw it might be, under the language they were adopting.” 
Fortunately for this nation, the five waivering Justices eventually came to their senses and discarded the "original" understanding of the 14th Amendment as irrelevant. Writing for a unanimous Supreme Court, Chief Justice Earl Warren observed the following:
In approaching this problem, we cannot turn the clock back to 1868, when the Amendment was adopted, or even to 1896, when Plessy v. Fergusonwas written. We must consider public education in the light of its full development and its present place in American life throughout the Nation. Only in this way can it be determined if segregation in public schools deprives these plaintiffs of the equal protection of the laws.
Desegregation via Brown is only one of the many indispensable products of a Living Constitution. Consider how the execution of juveniles or mentally retarded inmates is now considered "cruel and unusual punishment" under the 8th Amendment's "evolving standards of decency." Consider also the constitutional right to privacy, the right to interracial marriage, or the right to be free from warrantless searches - all of which were once unthinkable during earlier eras.
As our country continues to change for the better, so should the meaning of our Constitution.
In United States constitutional interpretation, the living Constitution (or loose constructionism) is the claim that the Constitution has a dynamic meaning or that it has the properties of an animate being in the sense that it changes. The idea is associated with views that contemporaneous society should be taken into account when interpreting key constitutional phrases.
While the arguments for the Living Constitution vary, they can generally be broken into two categories. First, the pragmatist view contends that interpreting the Constitution in accordance with its original meaning or intent is sometimes unacceptable as a policy matter, and thus that an evolving interpretation is necessary. The second, relating to intent, contends that the constitutional framers specifically wrote the Constitution in broad and flexible terms to create such a dynamic, "living" document. Opponents of the idea often argue that the Constitution should be changed through the amendment process, and that allowing judges to determine an ever-changing meaning of the constitution undermines democracy. The primary alternative to the Living Constitution is most commonly described as originalism.
Some supporters of the "living" method of interpretation, such as professors Michael Kammen and Bruce Ackerman refer to themselves as organicists.
The phrase originally derives from the title of a 1927 book of that name by Professor Howard Lee McBain, while early efforts at developing the concept in modern form have been credited to figures including Oliver Wendell Holmes Jr., Louis D. Brandeis, and Woodrow Wilson. The earliest mentions of the Constitution as "living", particularly in the context of a new way of interpreting it, comes out of Woodrow Wilson's book Constitutional Government in the United States where he wrote:
Living political constitutions must be Darwinian in structure and in practice.
Wilson strengthened this view, at least publicly, while he campaigned for President in 1912. He said:
Society is a living organism and must obey the laws of life, not of mechanics; it must develop. All that progressives ask or desire is permission - in an era when "development," "evolution," is the scientific word - to interpret the Constitution according to the Darwinian principle; all they ask is recognition of the fact that a nation is a living thing and not a machine.
One could also reasonably argue that Thomas Jefferson himself presented the idea of evolving Constitutional interpretations. In an 1816 letter to Samuel Kercheval, excerpted on Panel 4 of the Jefferson Memorial, he wrote
"But I know also, that laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths disclosed, and manners and opinions change with the change of circumstances, institutions must advance also, and keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy, as civilized society to remain ever under the regimen of their barbarous ancestors. 
Although "the living Constitution" is itself a characterization rather than a specific method of interpretation, the phrase is associated with various non-originalist theories of interpretation. The most common association is with judicial pragmatism. In the course of his judgment in Missouri v. Holland 252 U.S. 416 (1920), Holmes made this remark on the nature of the constitution.
With regard to that we may add that when we are dealing with words that also are a constituent act, like the Constitution of the United States, we must realize that they have called into life a being the development of which could not have been foreseen completely by the most gifted of its begetters. It was enough for them to realize or to hope that they had created an organism; it has taken a century and has cost their successors much sweat and blood to prove that they created a nation. The case before us must be considered in the light of our whole experience and not merely in that of what was said a hundred years ago. The treaty in question does not contravene any prohibitory words to be found in the Constitution. The only question is whether [252 U.S. 416, 434] it is forbidden by some invisible radiation from the general terms of the Tenth Amendment. We must consider what this country has become in deciding what that amendment has reserved.
According to the pragmatist view, the Constitution should be seen as evolving over time as a matter of social necessity. Looking solely to original meaning, when the original intent was largely to permit many practices universally condemned today, is under this view cause to reject pure originalism out of hand.
This general view has been expressed by Judge Richard Posner:
A constitution that did not invalidate so offensive, oppressive, probably undemocratic, and sectarian law [as the Connecticut law banning contraceptives] would stand revealed as containing major gaps. Maybe that is the nature of our, or perhaps any, written Constitution; but yet, perhaps the courts are authorized to plug at least the most glaring gaps. Does anyone really believe, in his heart of hearts, that the Constitution should be interpreted so literally as to authorize every conceivable law that would not violate a specific constitutional clause? This would mean that a state could require everyone to marry, or to have intercourse at least once a month, or it could take away every couple's second child and place it in a foster home.... We find it reassuring to think that the courts stand between us and legislative tyranny even if a particular form of tyranny was not foreseen and expressly forbidden by framers of the Constitution.
This pragmatist objection is central to the idea that the Constitution should be seen as a living document. Under this view, for example, constitutional requirements of "equal rights" should be read with regard to current standards of equality, and not those of decades or centuries ago, because the alternative would be unacceptable.
Main article: Original intent
In addition to pragmatist arguments, most proponents of the living Constitution argue that the Constitution was deliberately written to be broad and flexible to accommodate social or technological change over time. Edmund Randolph, in his Draft Sketch of Constitution, wrote this:
In the draught of a fundamental constitution, two things deserve attention:
- 1. To insert essential principles only; lest the operations of government should be clogged by rendering those provisions permanent and unalterable, which ought to be accommodated to times and events: and
- 2. To use simple and precise language, and general propositions, according to the example of the constitutions of the several states.
The living constitution's proponents assert that Randolph's injunction to use "simple and precise language, and general propositions," such that the Constitution could "be accommodated to times and events," is evidence of the "genius" of the Constitutional framers. James Madison, principal author of the U.S. Constitution and often called the "Father of the Constitution," said this in argument for original intent and against changing the Constitution by evolving language:
I entirely concur in the propriety of resorting to the sense in which the Constitution was accepted and ratified by the nation. In that sense alone it is the legitimate Constitution. And if that is not the guide in expounding it, there may be no security for a consistent and stable, more than for a faithful exercise of its powers. If the meaning of the text be sought in the changeable meaning of the words composing it, it is evident that the shape and attributes of the Government must partake of the changes to which the words and phrases of all living languages are constantly subject. What a metamorphosis would be produced in the code of law if all its ancient phraseology were to be taken in its modern sense.
Some living Constitutionists seek to reconcile themselves with the originalist view; e.g., one that interprets the Constitution as it was originally intended to be interpreted.
Applying a living constitution
One application of the living Constitution framework is seen in the Supreme Court's reference to "evolving standards of decency" under the Eighth Amendment. This was seen in the 1958 Supreme Court case of Trop v. Dulles:
[T]he words of the [Eighth] Amendment are not precise, and that their scope is not static. The Amendment must draw its meaning from the evolving standards of decency that mark the progress of a maturing society.
While the Court was referring in Trop only to the Eighth Amendment's prohibition on cruel and unusual punishment, the underlying conception – namely, that the Constitution is written in broad terms, and that the Court's interpretation of those terms should reflect current societal conditions – is the heart of the "living Constitution" doctrine.
Equal protection and due process clauses
See also: Fifth Amendment to the United States Constitution and Fourteenth Amendment to the United States Constitution
From its inception, one of the most controversial aspects of the living Constitutional framework has been its association with broad interpretations of the equal protection and due process clauses of the 5th and 14th Amendments.
Proponents of the Living Constitution suggest that a dynamic view of civil liberties is vital to the continuing effectiveness of our Constitutional scheme. Not only is it currently seen as unacceptable to suggest that married women or descendants of slaves are not entitled to liberty or equal protection with regard to coverture laws, slavery laws and their legacy as they were not expressly seen as free from such by all ratifiers at the time of the Constitutional ratification, but neither do advocates of the living Constitution believe that the framers intended, or certainly demanded, that their 18th century practices be regarded as the permanent standard for these ideals.
Living Constitutionalists suggest that broad ideals such as "liberty" and "equal protection" were included in the Constitution precisely because they are timeless, due to their inherently dynamic nature. Liberty in 1791, it is argued, was never thought to be the same as liberty in 1591 or 1991, but rather was seen as a principle transcending the recognized rights of that day and age. Giving them a fixed and static meaning in the name of "originalism," thus, is said to violate the very theory it purports to uphold.
Points of contention
As the subject of significant controversy, the idea of a Living Constitution is plagued by numerous conflicting contentions.
Disregard of Constitutional language
The idea of a Living Constitution was often characterized by Justice Scalia and others as inherently disregarding Constitutional language, suggesting that one should not simply read and apply the constitutional text.
Jack Balkin argues that this is not the intended meaning of the term, however, which suggests rather that the Constitution be read contemporaneously, rather than historically. Such an inquiry often consults the original meaning or intent, along with other interpretive devices. A proper application, then, involves some reconciliation between these various devices, not a simple disregard for one or another.
Another common view of the Living Constitution is as synonymous with "judicial activism," a phrase generally used to accuse judges of resolving cases based on their own political convictions or preferences.
In sum, it may be noted that the Living Constitution does not itself represent a detailed philosophy, and that distinguishing it from other theories can be difficult. Indeed, Living Constitutionalists often suggest that it is the true originalist philosophy, while originalists generally agree that phrases such as "just compensation" should be applied differently than 200 years ago. It has been suggested that the true difference between these judicial philosophies does not regard "meaning" at all, but rather, the correct application of Constitutional principles. A Living Constitutionalist would not necessarily state, for instance, that the meaning of "liberty" has changed since 1791. It may be what it always has always been: a general principle recognizing individual freedom. The important change then might be in what is recognized as liberty today, that was not fully recognized two centuries ago. This view was enunciated for the Supreme Court by Justice George Sutherland in 1926:
[W]hile the meaning of constitutional guaranties never varies, the scope of their application must expand or contract to meet the new and different conditions which are constantly coming within the field of their operation. In a changing world it is impossible that it should be otherwise. But although a degree of elasticity is thus imparted, not to the meaning, but to the application of constitutional principles, statutes and ordinances, which, after giving due weight to the new conditions, are found clearly not to conform to the Constitution, of course, must fall.
To complete the example, the question of how to apply a term like "liberty" may not be a question of what it "means," but rather a question of what liberties are presently entitled to constitutional protection. Living Constitutionalists tend to advocate a broad application in accordance with current views, while originalists tend to seek an application consistent with views at the time of ratification. Critics of the Living Constitution assert that it is more open to judicial manipulation, while proponents argue that theoretical flexibility in either view provides adherents extensive leeway in what decision to reach in a particular case.
By its nature, the "living Constitution" is not held to be a specific theory of construction, but a vision of a Constitution whose boundaries are dynamic, congruent with the needs of society as it changes. This method also has its critics; in the description of Chief Justice William Rehnquist, it "has about it a teasing imprecision that makes it a coat of many colors."
It is important to note that the term "living Constitution" is sometimes used by critics as an aspersion, while some advocates of the general philosophy avoid the phrase. Opponents of the doctrine tend to use the term as an epithet synonymous with judicial activism (itself a hotly debated phrase). However, just as some conservative theorists have embraced the term Constitution in Exile (which similarly gained popularity through use by liberal critics), and textualism was a term which once had pejorative connotations before its widespread acceptance as a badge of honor, some liberal theorists have embraced the image of a living document as appealing.
Arguments in favor
Two of the arguments in support of the concept of a "living Constitution" is the concept that the Constitution itself is silent on the matter of constitutional interpretation. Proponents of the living Constitution assert that the Constitutional framers, most of whom were trained lawyers and legal theorists, were certainly aware of these debates; they also would have known the confusion that not providing a clear interpretive method would cause. Had the framers meant for future generations to interpret the Constitution in a specific manner, they could have indicated such within the Constitution itself. The lack of guidance within the text of the Constitution suggests, therefore, that either: a) there was no such consensus, or b) the framers never intended any fixed method of constitutional interpretation.
Relating to the pragmatic argument, it is further argued that if judges were denied the opportunity to reflect on changes to modern society in interpreting the scope of Constitutional rights, the resulting Constitution either would not reflect current mores and values, or would necessitate a constant amendment process to reflect our changing society.
Another defense of the Living Constitution is based in viewing the Constitution not merely as law, but as a source of foundational concepts for the governing of society. Of course, laws must be fixed and clear so that people can understand and abide by them on a daily basis. But if the Constitution is more than a set of laws, if it provides guiding concepts which themselves will in turn provide the foundations for laws, then the costs and benefits of such an entirely fixed meaning are very different. The reason for this is simple: if a society locks itself into a previous generation's interpretive ideas, it will wind up either constantly attempting to change the Constitution to reflect changes, or simply scrapping the Constitution altogether. While we remain bound by the rights and powers provided in the Constitution, thus, the scope those rights and powers should account for society's present experiences. "Oliver Wendell Holmes, Jr., wrote in 1914: 'Provisions of the Constitution of the United States are not mathematical formulas having their essence in their form, but are organic living institutions transplanted from English soil. Their significance is not to be gathered simply from the words and a dictionary, but by considering their origin and the line of their growth.'"
A prominent endorsement of the Living Constitution concept was heard in the 2000 presidential campaign by the Democratic candidate, Al Gore.
The strongest argument against the doctrine of "Living Constitution" comes not from its moderate use, but when the concept is seen as promoting activism. The term presumes the premise of “that which is written is insufficient in light of what has transpired since”. This more moderate concept is generally not the target of those who are against the "Living Constitution". The concept considered perverse by constructionalists is "making the law say what you think it should say, rather than submitting to what it does say".
Economist Thomas Sowell argues in his book Knowledge and Decisions that since the original designers of the Constitution provided for the process of changing it, they never intended for their original words to change meaning. Sowell also points out cases where arguments are made that the original framers never considered certain issues, when clear record of them doing so exists.
Another argument against the concept of a "living Constitution" ironically, is similar to the argument for it; the fact that the Constitution itself is silent on the matter of constitutional interpretation. The doctrine of the "living Constitution" relies on the concept that the original framers either could not come to a consensus about how to interpret, or they never intended any fixed method of interpretation. This would then allow future generations the freedom to reexamine for themselves how to interpret the Constitution.
This view does not take into account why the original constitution does not allow for judicial interpretation in any form. The Supreme Court's power for constitutional review, and by extension its interpretation, did not come about until Marbury v. Madison in 1803. The concept for a "living constitution" therefore relies on an argument regarding the writing of the constitution that had no validity when the constitution was written.
The views of constitutional law scholar Laurence Tribe are often described by conservative critics such as Robert Bork as being characteristic of the “living Constitution paradigm” they condemn. Bork labels Tribe’s approach as "protean," meaning that it was whatever Tribe needed it to be to reach a desired policy outcome. (Tribe rejects both the term and the description) Such a construction appears to define “living Constitution” doctrine as being an ends dictate the means anti-law philosophy. Some liberal constitutional scholars have since implied a similar charge of intellectual dishonesty regarding originalists, noting that they virtually never reach outcomes with which they disagree. (Many academic political scientists believe that justices and appeals judges are willing to alter their outcomes to attain philosophical majorities on certain questions.)
In 1987, Supreme Court Justice Thurgood Marshall delivered a lecture, "The Constitution: A Living Document," in which he argued that the Constitution must be interpreted in light of the moral, political, and cultural climate of the age of interpretation. If Judge Bork's formulation of "the living Constitution" is guiding, then any interpretation of the Constitution other than originalism (of one form or another) implicates a living Constitution. If, however, Justice Marshall's formulation is guiding, then it is unclear whether methods derived from law and economics or the Moral Constitution might be implicated.
References to "the living Constitution" are relatively rare among legal academics and judges, who generally prefer to use language that is specific and less rhetorical. It is also worth noting that there is disagreement among opponents of "the living Constitution" about whether the idea is the same as, implied by, or assumed by judicial activism, which has a similar ambiguity of meaning and is also used primarily as an epithet.
Justice Clarence Thomas has routinely castigated "living Constitution" doctrine. In one particularly strongly worded attack, he noted that:
Let me put it this way; there are really only two ways to interpret the Constitution – try to discern as best we can what the framers intended or make it up. No matter how ingenious, imaginative or artfully put, unless interpretive methodologies are tied to the original intent of the framers, they have no more basis in the Constitution than the latest football scores. To be sure, even the most conscientious effort to adhere to the original intent of the framers of our Constitution is flawed, as all methodologies and human institutions are; but at least originalism has the advantage of being legitimate and, I might add, impartial.
Justice Antonin Scalia has expressed similar sentiments. He commented:
[There's] the argument of flexibility and it goes something like this: The Constitution is over 200 years old and societies change. It has to change with society, like a living organism, or it will become brittle and break. But you would have to be an idiot to believe that; the Constitution is not a living organism; it is a legal document. It says something and doesn't say other things.... [Proponents of the living constitution want matters to be decided] not by the people, but by the justices of the Supreme Court .... They are not looking for legal flexibility, they are looking for rigidity, whether it's the right to abortion or the right to homosexual activity, they want that right to be embedded from coast to coast and to be unchangeable.
He also said:
If you think aficionados of a living Constitution want to bring you flexibility, think again.... You think the death penalty is a good idea? (Under the formalist understanding of the Constitution, but not under the Living Constitution understanding, you can) persuade your fellow citizens to adopt it. You want a right to abortion? Persuade your fellow citizens and enact it. That's flexibility.
One accusation made against the living Constitution method states that judges that adhere to it are "Activists" and seek to legislate from the bench. What is generally meant by this is that a judge winds up substituting his judgment regarding the validity, meaning, or scope of a law for that of the democratically elected legislature.
Adherents of a living Constitution method are often accused of "reading rights" into the Constitution; that is, they are accused of claiming that the Constitution implies rights found nowhere in the constitutional text. For example, in Roe v. Wade, the Supreme Court held that implicit within the Constitution was a "right to privacy" and that this right extends to a woman's right to decide whether to terminate a pregnancy. As such, the Court held that the government could only regulate this right with a compelling interest, and even then, only if the regulation was as minimally intrusive as possible. Conservative critics have since accused the Supreme Court of activism in inventing a Constitutional right to abortion. This accusation may be accurate (in that abortion rights indeed had not previously been recognized), however as a criticism made by conservatives, it has been applied selectively. For example, few conservatives levy the same claim against the Supreme Court for its decisions concerning sovereign immunity: a term also found nowhere in the Constitution but has been read into the Eleventh Amendment by the Supreme Court and since been expanded by the recent conservative majority.
In Canada, the living constitution is described under the living tree doctrine.
Unlike the case of the United States, the fact that the constitution of Canada was intended from the outset to encompass unwritten conventions and legal principles is beyond question. For example, the text of the constitution does not mention the office of prime minister or that the governor general always grants royal assent to bills. Principles such as democracy, the Implied Bill of Rights, the rule of law, and judicial independence are held to derive in part from the preamble of the constitution, which declared the constitution of Canada to be "similar in principle" to that of the United Kingdom.
The concept of an evolving constitution has notably been applied to determine the division of powers between provinces and the federal government in areas of jurisdiction not contemplated at the time of enactment of the British North America Act. For example, authority over broadcasting has been held to fall within the federal "peace, order and good government" power.
The Supreme Court of Canada, in Re: Same-Sex Marriage (2004), held that Parliament (as opposed to provincial legislatures) had the power to define marriage as including same-sex unions. It rejected claims that the constitutionally enumerated federal authority in matters of "Marriage and Divorce" could not include same-sex marriage because marriage as conceived in 1867 was necessarily opposite-sex:
The "frozen concepts" reasoning runs contrary to one of the most fundamental principles of Canadian constitutional interpretation: that our Constitution is a living tree which, by way of progressive interpretation, accommodates and addresses the realities of modern life.
It has been argued that a primary determinative factor in whether a legal system will develop a "living constitutional" framework is the ease with which constitutional amendments can be passed. With this view in mind, the UK Constitution could be considered a "living constitution". It only requires a simple majority vote  to amend. Like the Canadian constitution, the UK constitution is an Uncodified constitution.
The Constitution of India is considered to be a living and breathing document.

- ^Sunsetin, Cass (2006). Of Snakes and Butterflies: A Reply. 106 Columbia Law Review 2234. ("In the last decade and more, some (of course very far from all) conservative judges have been reading the Constitution in a way that lines up uncomfortably well with their own political views: to invalidate affirmative action programs, campaign finance laws, and restrictions on gun control; to strike down certain laws protecting the environment and forbidding discrimination on the basis of disability and age; to protect commercial advertising; to permit discrimination on the basis of sex and sexual orientation; to allow government to provide financial and other assistance to religious institutions; to give the President broad, unilateral authority to fight the war on terror; and to contain no right of reproductive choice or sexual liberty. No one doubts that some of these readings of the Constitution are reasonable. But Radicals in Robes was partly designed to show that, for all the talk of "strict construction," and for all the insistence on distinguishing between law and politics, we are in the midst of a period in which some prominent conservatives are attempting to use judicial power for their own political ends. To be sure, judges almost always act in good faith. But it is nonetheless true that references to history, and to the views of the Framers and ratifiers, are sometimes a fraud and a façade.")

August 29, 2005 http://www.slate.com/id/2125226/ Retrieved 4/20/07 ("Because the basic jurisprudential claim that original understanding is the only legitimate method of interpretation is overstated, originalists usually make a second, more pragmatic argument: A living Constitution offers insufficient constraints on judicial power. The irony of this charge is that in practice originalism doesn't provide any greater constraint. As we've seen, originalist judges pick and choose when to invoke original understanding and when to rely on existing precedents they like.")
