The correct reading だんがい uses standard On'yomi. 弾 (ダン) means to censure and 劾 (ガイ) means to investigate/impeach. This term refers to the formal process by which a legislative body brings charges of misconduct against a public official, potentially leading to their removal from office.

正しい読みは「だんがい」で、両方とも音読みです。「弾」は弾劾、劾」は不正を究明することを意味します。主に議会が、不正を行った公務員（特に高官）に対し、職務上の責任を追及し、罷免を求める手続きを指します。
