Former Malaysian Bar president Ambiga Sreenevasan said immediate and decisive action by lawyers is needed in the face of attacks on the judiciary.

She said this in explaining a petition started by her and five other former Bar presidents calling on the Bar Council to mobilise a "Walk for Justice" similar to what was done in 2007 when allegations of judicial fixing emerged.

"This petition was launched to urge the Bar Council to hold a walk by members of the Bar sooner rather than later.

"There are moments in time that require an immediate and decisive response from the lawyers and this is one of them," she told Malaysiakini.
