Pittsburgh City Council waylaid Councilman Bill Peduto's attempt to investigate how city planners approved a 1,200-square-foot electronic sign without a required public review. Peduto's motion to turn council into a "quasi-judicial board" that could publicly question Mayor Luke Ravenstahl, Planning Director Noor Ismail and others failed to muster support from his colleagues and was set aside for a post-agenda hearing scheduled for Wednesday. "I don't believe personally that you just jump into council conducting an investigation," said Councilman Jim Motznik, who opposed Peduto's motion.
