Dr Brown's legal counsel Roland Browne filed a writ on Wednesday, challenging the Workplace (Protection from Protesters) Act 2014 on the basis it contravenes the constitutional rights of citizens.

He was charged under the law when he protested against the logging of a coupe at Lapoinya in January.

Dr Brown will appear in the Hobart Magistrates Court on Friday.

Five protesters have been arrested at Lapoinya since the laws were adopted.

Dr Brown's High Court challenge is the first against the controversial legislation. 

He said the law was draconian, and impinged on the right to peaceful protest and freedom of speech. 

Dr Brown said he was concerned the laws could be introduced by other state jurisdictions.

''It's justified and compelling that we make this stand, otherwise we're in a country where we're going to see the serial prohibition on people simply expressing their beliefs in the democratic system.''

''The Premier and his minister [former Resources Minister Paul Harriss] said these laws weren't to trap mums and dads, but they did. First up they trapped a young mother and nurse who grew up in the Lapoinya area and a local grandfather.

The laws will, if not challenged, trap everybody who wants to take a stand against something that's manifestly wrong going on in our country.'' 

Comment is being sought from the Tasmanian government.
