AUDIT 101: SAIs’ mission, structure, mandate, and various models
Ex-Ante & Ex-Post Auditing
Molded by different institutional arrangements, SAIs vary in terms of their features and functions. Whereas some oversight agencies are collegiate bodies, others respond to a monocratic structure. Similarly, fiscal control can occur before (ex-ante) or after (ex-post) the acts of the administration take place.
Ex-ante auditing verifies the legality of administrative actions before they are implemented, thereby acting as a potential veto on administrative discretion and placing its focus on mismanagement prevention. Over the past few years, SAIs have begun to move away from pre-audit work or reduce its importance in comparison to ex-post auditing.
Ex-post auditing examines government undertakings, operations, programs, and activities after their implementation, leading to corrections and even punishment for wrongdoing. Performance audits are exclusively ex-post, and they have been the general trend of the past few years, encompassing a stronger emphasis on accountability with managerial objectives rather than solely focusing on compliance with legal regulations.
