Meaning of judgment call

judg'ment call"

Pronunciation: [key]
  1. an observational ruling by a referee or umpire that is necessarily subjective because of the disputable nature of the play in question, and one that may be appealed but not protested, as opposed to a matter of official rule interpretation: Balks and close plays at first are of course judgment calls, and umpires are human.
  2. any subjective or debatable determination; personal opinion or interpretation.
