Bob Brown wins high court challenge to Tasmanian anti-protest laws

Judgment rules laws unconstitutional after former Greens leader argues they interfered with the right to freedom of political expression

The former Australian Greens leader Bob Brown has won a landmark high court fight against Tasmanian anti-protest laws passed in 2014 and under which he was charged in 2016.

Brown, the third person arrested under the Workplaces (Protection from Protesters) Act 2014, argued the laws directly targeted implied freedom of political expression in the constitution and were therefore unconstitutional.
