change a decision

What's the word for when an important decision is re-thought through and the conclusion is changed ?

E.g.

I didn't expect you to retroactively ______ the decision (turns out this was the wrong noun too)

I guess in this case it can be synonymous with veto.

I think the word I am looking for starts with "re", like rebuke or refute etc. but it just means to re-decide. Something like revoke.


Solution 1:

For me it would be rescind.

Meaning: revoke, cancel, or repeal (a law, order, or agreement)

Ex. The government eventually rescinded the directive.
