The City Council voted Friday to modify and clarify the intent of a previous resolution that created a "Clean Zone" during the Major League Baseball All-Star Game.

The amended resolution comes a day after organizers of a 1934 Teamsters Strike commemoration sued the city, alleging that the council had ceded too much power to the MLB over events held during the All-Star Game, infringing on their First Amendment rights.

The original language stated that no temporary licenses or permits could be approved in designated areas of the city "without additional approval of Major League Baseball." The new language, which passed unanimously Friday, says the city will not grant such permits or licenses "without conferring with Major League Baseball."

"The original resolution seemed to indicate that the Major League Baseball had a role in [the approval]," amendment sponsor council member John Quincy said Friday. "I wanted to make sure that everybody knew this amendment said Major League Baseball would be conferred with, but the city retains those authorities."

The timeline of the "Clean Zone" were also shortened from 15 days to 6 days, starting on July 10.

Additionally, the language makes clear that the city retains the full authority to grant or deny temporary permit or license applications. "It is the city's intention that constitutional rights will preempt other considerations," the resolution says.

Regarding the Teamsters events -- a parade and block party -- the city has said that they anticipate routinely approving both permits.

Here is the full amended resolution:
