To cancel or countermand a previous action is known as what?

The term "rescind" specifically refers to the act of canceling or nullifying a previous action, decision, or agreement. In various contexts, such as legal, parliamentary procedure, or organizational rules, to rescind means to revoke or withdraw a prior resolution or action formally. This is applicable when decisions need to be reversed due to new information, changes in circumstances, or errors in the original action.

While the other terms have their own meanings, they do not encompass the idea of canceling an action. "Amend" refers to making changes or modifications to a document or action, "commit" generally means to authorize or dedicate someone or something to a particular function, and "question" is about challenging or inquiring into something rather than canceling it. Therefore, rescind directly aligns with the intent of reversing a prior decision.
