Through the use of Lockean philosophy concerning the nature of man, the Constitutional rights will always pertain to the needs of society, despite the fact that such thought is nearly three hundred years old. The Constitution also regulates the powers of each governmental structure by allowing a system of checks and balances to emerge. The continuing growth of government in recent years causes more legislation, but ultimately preserves civil right and liberties through such growth. The Supreme Court is able to mold public policy with every decision it hands down on every case it oversees. The relevancy of the Constitution is quite clear in the everyday lives of each American, and it establishes itself as the "supreme law of the land" on a regular basis.
