Courts do not throw out criminal complaints (or for that matter, contracts, settlements, plea deals, etc.) because of a "typo" or what is known in the law as a "scribner's error": e.g. an obvious harmless error ("harmless" because it is readily determinable what the error *should* have said--i.e. the correct date) made in typing, writing, signing, or transcribing. So this would not require the complaint to be thrown out, and it is still valid.
