不予 (bùyǔ) is a formal, written phrase meaning 'to not give, withhold, or decline to (do something)' — it always appears directly before a verb (e.g., 不予受理). It is more formal and rigid than 拒绝 (jùjué 'refuse'), and broader than 扣 (kòu 'deduct money' or 'withhold' something specific). Unlike 抵制 (dǐzhì 'boycott'), 不予 simply states a refusal or withholding without implying active opposition.
