The main purpose of the Limiting Excessive Government Obstruction Act is to streamline the process for certain agency adjudications, which are formal decisions made by government agencies. This legislation aims to reduce delays and obstacles in these proceedings, making it easier for parties involved to navigate the system. Key provisions of the Act include the introduction of a mechanism called a demurrer, which allows a party facing an agency adjudication to file a request for dismissal. If this request is made, the adjudicator must issue a final order dismissing the case.
