Dismissal for pretrial delay in non-capital cases requires demonstrating both government responsibility for delay and actual prejudice under Article 10 and the Sixth Amendment. Article 10 demands speedy disposition of charges, creating higher standards than constitutional requirements. The burden shifts to the government to show reasonable diligence in processing cases once the defense demonstrates facially unreasonable delay. Rigid time limits don’t exist; analysis considers case complexity, cause of delays, and prejudice severity.
Under constitutional analysis, courts apply the four-factor Barker test: length of delay, reasons for delay, assertion of rights, and prejudice. Delays exceeding 120 days trigger presumptive constitutional concern. Government-caused delays weigh heavily against prosecution, while defense requests or neutral factors like operational deployments receive less weight. Prejudice includes oppressive pretrial confinement, anxiety beyond normal levels, and impaired defense preparation through lost evidence or witnesses.
Dismissal remains an extraordinary remedy requiring egregious violations. Lesser remedies include sentence credit, suppressing evidence obtained through delay, or limiting government evidence. The analysis examines cumulative delay from preferral through trial, not individual processing stages. Post-trial delays receive separate analysis under different standards. Defense counsel must document specific prejudice beyond conclusory claims, particularly regarding lost evidence or witness unavailability. Systematic delays suggesting command indifference to speedy trial rights strengthen dismissal arguments over isolated processing delays.
