I’m pretty sure that the following expression is quite common to have someone else make the decision in everyday speaking.
It's your call.
Ngram Viewer justifies it.
The graph also indicates that the negative version of it is much less common than its positive version.
It's not your call.
However, the statistic is based upon written English.
In real life, is it common to say "it's not your call" in speaking?
Best Answer
Yes, it is fine in spoken English. In fact you should find it is more common in speech.
Note that "It's your call" means "It is your decision to make". So "It's not your call" means "It is not your decision to make". So it is a slightly argumentative phrase. You are exerting authority over someone.
