The grammar pattern によらず means "regardless of", "irrespective of", or "no matter what". It is used to express that something applies universally, without being affected or limited by the noun it attaches to. It is a formal expression commonly found in written language, official announcements, rules, and academic contexts.
によらず attaches directly to a noun and indicates that the outcome or statement holds true no matter what value or category that noun takes.
によらず is frequently paired with question-word-based expressions like なん何、だれ誰、どこ etc. to emphasize that absolutely no exceptions exist.
によらず carries the nuance that the noun it modifies is not used as a criterion or basis for judgment. It literally stems from the negative form of よる (to depend on / to be based on), so it conveys "not depending on ~" or "not based on ~".
