Paul O'Connor, who supervises prosecutors handling misdemeanor Circuit Court cases, said lowering penalties for possessing small quantities of marijuana to under 90 days in jail would reduce jury trial requests by 15 percent to 20 percent in Baltimore. But rural and suburban counties, which can manage their caseloads, have resisted legislative efforts to reduce marijuana possession penalties, he said.
In the 1980s, one district judge, Robert J. Gerstung, tried to bypass the legislature by promising not to send defendants to jail for more than 89 days on the condition that they wouldn't request a jury trial. In three opinions that decade, the Court of Appeals ruled the "Gerstung Rule" unconstitutional.
After legislative attempts to reverse the court failed, instant jury trials began.
