It is based on a review of information developed by the Department of Justice and by the Administrative Office of the Court. Following a review of the requirements of the Speedy Trial Act, this report discusses the current levels of compliance with the act's final time limits, summarizes the apparent causes of noncompliance, attempts to identify the more significant apparent 'costs' of compliance as they relate to the due administration of justice, and assess the major proposals for modification of the act. Findings indicate that the degree of compliance with the act was relatively high for the year ending June 30, 1978, that overall compliance with the act's ultimate time limits was equally high, that the most significant source of delay was time spent considering plea offers, and that the most significant cost of compliance with the act is continued and aggravated delay in the disposition of civil cases. Footnotes are included. (Author summary modified)
