A meeting of the nation's top law officials this week may consider changing the way juries are instructed or restricting social media in the wake of events surrounding Jill Meagher's death, Victorian Premier Ted Baillieu says.
Attorneys-general from across the nation will meet in Brisbane on Friday to discuss the challenges social media pose to the fair conduct of jury trials.
Police are concerned prejudicial comments posted on Facebook could jeopardise the case against Adrian Ernest Bayley, 41, who is accused of raping and murdering Ms Meagher in Melbourne.
Facebook finally removed several hate pages targeting Bayley on Wednesday, after days of repeated requests from Victorian authorities.
Mr Baillieu stressed there must be a national approach to resolve issues around social media and the legal process.
'It's important to tackle this at a national level,' he told reporters in Melbourne on Wednesday.
He said the attorneys-general may consider social media education and possible constraints.
Another possibility would be to change the law on how juries were instructed, Mr Baillieu said.
'To the extent that this now has the capacity to impact on a trial system we need to address that and address it quickly,' he said.
