Futility Closet, "an idler's miscellany of compendious amusements," quotes legal scholar Mark V. Tushnet explaining by way of example that there's no element of the constitution, no matter how apparently obvious, that does not require interpretation:

“Suppose that the guru’s supporters sincerely claim that their religion includes among its tenets a belief in reincarnation. Even on the narrowest definition of ‘age,’ they say, their guru is well over thirty-five years old even though the guru emerged from the latest womb sixteen years ago.

“Further, it would have been an establishment of religion for the President of the Senate to reject their definition of ‘age,’ and it would violate their rights under the free exercise clause … for the courts to overturn the decision made by the political branches.”
