de minimis non curat praetor

The commander does not bother with the smallest things.

Notes

Also "The chief magistrate does not concern himself with trifles." Trivial matters are no concern of a high official (cf. aquila non capit muscas, the eagle does not catch flies). Sometimes rex (the king) or lex (the law) is used in place of praetor, and de minimis is a legal term referring to things unworthy of the law's attention.
