 The United States Congress lacks the ability within the Constitution to impose upon American citizens a duty to kneel daily before a cross. Since the Congress lacks a power, the citizens have an immunity. This immunity is a core element of an American citizen’s right to religious freedom. Similarly, witnesses in court have a right not to be ordered to incriminate themselves, and civil servants have a right not to be dismissed when a new government comes to power. All of these rights are immunities, corresponding to an absence of a power in some other party to alter the rightholder’s normative situation in some way.
