The WA Liberal Party has launched its second Supreme Court challenge against local governments that ban political signs on private property for the State election campaign.
The party has challenged the validity of the City of Gosnells town planning scheme that prohibits political signs except those of a certain size within 28 days before the election.
It also has challenged a council planning document that does not allow third party advertising.
The party is arguing the bans impinge on the implied constitutional right to free political communication. The action against Gosnells comes after the Liberals won an injunction against the City of Armadale last month to allow it to continue to display signs after the council ordered they be removed.
The two test cases could have big implications for political advertising in WA. Chief Justice Wayne Martin said yesterday the City of Gosnells had written to the party saying that it could apply to erect signs but it need not bother because it conflicted with its policy.
He said he was keen to deal with the Gosnells challenge on a permanent basis.
