The courts are interested in any clues about the Constitution's meaning which they can find in the Preamble.[5] Courts have developed several techniques for interpreting the meaning of statutes and these are also used to interpret the Constitution.[6] As a result, the courts have said that interpretive techniques which focus on the exact text of a document[7] should be used in interpreting the meaning of the Constitution and so the Preamble provides additional language against which to compare other parts of the Constitution. Balanced against these techniques are those that focus more attention on broader efforts to discern the meaning of the document from more than just the wording;[8] the Preamble is also useful for these efforts to identify the "spirit" of the Constitution.
