A federal judge is hearing arguments today on a preliminary injunction requested by six groups seeking permit applications to hold events during the week of the G-20 summit.

U.S. District Judge Gary L. Lancaster called for a lunch break during the testimony of Michael Radley, an assistant director with Pittsburgh's Parks Department and the coordinator of the Great Race, to be held on Sept. 27.

The three issues that the plaintiffs are asking Judge Lancaster to decide include: Ordering the city to issue a permit for CodePink and Three Rivers Climate Convergence to use Point State Park from 6 p.m. Sunday to 6 p.m. on Tuesday; to give the Thomas Merton Center a route through Downtown for a march that would end at the Seventh Street Bridge with a rally; and to allow camping for various groups at Schenley Park during the week of the summit.

During his testimony, Mr. Radley said that he was asked by city Public Safety Director Michael Huss to push back setup for the Great Race until Sept. 24 to allow an event hosted by state Sen. Jim Ferlo to be held in Point State Park next Wednesday.

"It was agreed we could share the park," Mr. Radley said. "I had no objections."

Mr. Ferlo's group filed his permit application on Aug. 10. CodePink and Three Rivers Climate Convergence filed their applications for special events permits after Aug. 14.
