Immunities, conversely, are claim rights regarding the modification of first-order rights, e.g. U.S. citizens have, per their Constitution, certain immunities limiting the positive powers of the U.S. Congress to modify their legal rights.
On the other hand, immunities represent claims regarding the modification of fundamental rights, for instance, U.S. citizens possess, according to their Constitution, specific immunities that restrict the ability of the U.S. Congress to alter their legal rights.
