After restructuring the rules for mass tort cases, First Judicial District leaders are projecting a decrease in suits begun this year, Judge John W. Herron, the administrative judge of the common pleas court’s trial division, told the annual meeting of the Philadelphia Association of Defense Counsel this week.

Herron, along with Judge Sandra Mazer Moss, co-coordinating judge of the mass tort program, and Judge Arnold L. New, the other co-coordinating judge of the Complex Litigation Center — and who is set to succeed Moss as the sole coordinating judge at the end of the year — provided an update on measures the court has taken since the winter to change the mass tort program.
