The Malaysian Bar is gathering evidence for a legal challenge after police blocked hundreds of lawyers at Padang Merbok earlier today from proceeding with a planned 'Walk for Justice' to Parliament.

Bar Council president Karen Cheah said the evidence-gathering process to determine their next course of action will involve viewing footage from the ground as well as interviews with witnesses among lawyers present for the march.

"We will not sit down quietly. We are definitely taking it to court," said Cheah during a press conference at the Bar Council this afternoon, several hours after the cancelled march.
