"Re-pealing" refers to the act of canceling or revoking a law, regulation, or system that previously existed. Some possible antonyms for "re-pealing" could include "establishing," "enacting," "introducing," "implementing," "enforcing," or "ratifying." These words imply the creation or adoption of a new law or policy, rather than the rejection or annulment of an existing one. Other antonyms might include "extending," "continuing," or "renewing," which suggest the perpetuation or expansion of an existing policy or law. The choice of antonym would depend on the context in which "re-pealing" is being used and the specific meaning being conveyed.
