A senior solicitor involved in the successful Andrew Bolt racial discrimination case says US social networking giant Facebook has broken Australian law by hosting a controversial page dedicated to vilifying Aboriginal people.

Joel Zyngier, a senior associate with Holding Redlich, told Crikey this morning the site appears to be breach of section 18C of the Racial Discrimination Act that prohibits an act that "offend, insult, humiliate or intimidate another person or a group of people" on the grounds of race.
