GOLDSTEIN AND MARCUS PUBLISHED A STUDY OF THE CONTINENTAL CRIMINAL PROCESS IN 1977. THEY NOTED CONCERN IN THE UNITED STATES ABOUT OVERLY BROAD PROSECUTORIAL DISCRETION, A GROWING MISTRUST OF PLEA BARGAINING, AND CONTINUING DOUBT OVER THE EFFECTIVENESS OF EXCLUSIONARY RULES. INTERVIEWS WERE CONDUCTED IN THE COURSE OF THE STUDY WITH PROSECUTORS, JUDGES, DEFENSE ATTORNEYS, AND SCHOLARS IN FRANCE, GERMANY, AND ITALY. FROM THESE INTERVIEWS, IT WAS CONCLUDED THAT JUDGES IN INQUISITORIAL SYSTEMS DO NOT CONTROL OR SUPERVISE THE INVESTIGATION, PROSECUTION, OR TRIAL OF MOST CRIMINAL CASES MUCH MORE CLOSELY THAN JUDGES IN THE U.S. ADVERSARIAL SYSTEM. INVESTIGATION WAS GENERALLY LEFT TO POLICE AND, DESPITE STATUTORY PROHIBITIONS TO THE CONTRARY, CHARGING DISCRETION WAS EXERCISED FREQUENTLY AND WITHOUT SIGNIFICANT SUPERVISION BY POLICE AND PROSECUTORS. ALTHOUGH PLEA BARGAINING AS SUCH DID NOT OCCUR, ANALOGOUS PROCESSES BY WHICH PROSECUTORS AND DEFENDANTS MADE SIMILAR ACCOMMODATIONS THROUGH 'TACIT UNDERSTANDINGS OR PATTERNS OF RECIPROCAL EXPECTATION' WERE FOUND. THE FINDINGS OF THE STUDY SUGGEST THE NEED TO LEARN MORE ABOUT LIMITATIONS EXPERIENCED BY JUDGES AND OTHER OFFICIALS AND INDICATE THE IMPORTANCE OF ASSESSING THE RISK THAT JUDICIAL CONTROL MAY POSE IN CRIMINAL PROCEEDINGS. THE SIGNIFICANCE OF THE STUDY OF EUROPEAN PROCEDURES FOR CRIMINAL JUSTICE IN THE UNITED STATES IS EXAMINED BY THE ORIGINATORS OF THE STUDY AND IN RESPONSE TO CRITICISMS OF THE STUDY BY LANGBEIN AND WEINREB.
