棄却

1. Origins, structure, and basic meaning

• Structure: 棄却 is read as ききゃく and functions as a noun or with する for a court or committee formally dismissing a suit, claim, or application.
• Basic usage: The deciding body is the subject, the rejected matter takes を in 訴えを棄却する, and the grounds can be called 棄却理由.

2. Common pitfalls and similar expressions

• Formal procedural term
  • It belongs to legal or administrative decisions and is narrower than everyday 断る, which can mean refusing a personal request.
• Do not overstate legal contrasts
  • It often concerns rejection after consideration, but the precise distinction from 却下 depends on the terminology of the relevant procedure.
