The Constitution cannot be changed. The rules an provisions may be amended from time to time for clarification, but only so long as the amendment is not in direct conflict with the original intent of the founding document. If an amendment is in conflict with a rule or principle expressed in the Constitution it is unconstitutional, and therefore null and void from the time of its passage.
Sometimes Congress passes laws that are in conflict with the Constitution. Should this happen, the Supreme Court will place a ruling on the law making it void. This is because the US constitution is the supreme law of the country, and no law is allowed to go against it.

It is this power which actually allows the court system to uphold the constitution as the supreme law of the land. It judges all laws against that of the constitution. if there is discrepancy, it is not the constitution that changes, but the law in question. The Supreme Court can find a law passed either by Congress or any of the states conflicts with the constitution and declare that it is invalid and of no force or effect. The Court has no power to simply do this on its own. The issue must come to it via a proper lawsuit which alleges that the law unconstitutionally harms a protected right. This is called the power of "judicial review". An example is the case of Gibbons v. Ogden, which involved a claim that a New York law that gave a person exclusive rights to run a ferry service between New York and New Jersey. The Supreme Court ruled that the New York law was in conflict with the provision of the Constitution that gives Congress the sole power to regulate interstate commerce. The Court ruled the law was unconstitutional and not binding because the Constitution is supreme over state laws.
The United States Constitution always, always, always trumps any state constitutions. When there is a conflict, and that conflict comes into play in a court action, the court is bound to give force to the US Constitutional provision and invalidate the state constitutional provision.
A Supreme Court judgment on this point says that a rule will prevail over the provision if there is a conflict. Further in order to be a valid rule, the rule has to qualify the publication and shouldn't be against the public policy, constitution and parent Act.
