The Canberra Liberals have faced sanctions over another breach of election signage regulations.

Territory and Municipal Services (TAMS) impounded 30 Liberal Party signs that were illegally placed around Lanyon on Saturday.

The Liberals were also warned about incorrectly placed signage at Charnwood.

It is the second time TAMS has impounded Liberal Party signs, after another breach earlier this month.

The party must pay more than $100 per sign if it wants them returned.

ACT Labor branch secretary Elias Hallaj says the breach is disappointing but not surprising.

"I'm very disappointed that there's been another blatant breach of the rules by Zed Seselja's ACT Liberals," he said.

"It's a sign of arrogance that despite repeated warnings they continue to breach the rules in lots of different areas."

The Liberal Party has released a statement saying the signs were not attached to public property.

"The Liberal Party Campaign made a complaint about Labor Party signs, and no action was taken by the Government," the statement reads.

"The ranger said his reason for removing Liberal Party signs was that it was more than eight weeks out from the election.

"It's interesting the Labor Party has taken this line, given some Your Rights at Work posters are still attached to public property."

But TAMS says it has not received any complaints about Labor Party election signage.

A Liberal spokesman refused to say which signs the party complained about and when the complaint was made.
