Chief Magistrate Janelle Brassington on Thursday ruled against it taking place, removing legal protections for participants and ensuring police have the power to charge or arrest protesters if they obstruct traffic.

“It will inhibit access to major hospitals in Brisbane and to fire crews.”

Brassington said there was uncontested evidence the march could be held on an alternative route used for other protests but did not involve crossing the Story Bridge.

Justice for Palestine rally organisers had earlier indicated they would defy any court order and go ahead with the bridge protest to highlight the humanitarian crisis in Gaza.

Queensland Police assistant commissioner Rhys Wildman said there was insufficient fencing to stop protesters climbing from the bridge’s road lanes to its footpaths, which were unsafe.

The march aimed to mirror a recent demonstration across Sydney’s Harbour Bridge in which nearly 100,000 people attended in a sea of ponchos amid wet weather.
