As verbs the difference between rescind and revoke is that
rescind is to repeal, annul, or declare void; to take (something such as a rule or contract) out of effect while
revoke is to cancel or invalidate by withdrawing or reversing.
.
So rescind means the rule is now void, not used, no longer applied, but revoke means the rule no longer exists.
This seems rather subtle and similar in effect.
