1) There wasn't any need for an authorization for this minor surgery.
2) There wasn't any need of an authorization for this minor surgery.


Could you please check my sentences tell me whether "for" should be used here or "of"?

The original used "was" so I'd stick with the past tense for any suggested alternatives. I'm sure @tufguy had a reason for putting the sentence in the past.
