Vic Labor has power to stop East West Link

Labor is refusing to rule out using its numbers in the Victorian parliament to stop contracts to build the East West Link tunnel being signed.

Balance-of-power MP Geoff Shaw has spoken out against the $8 billion road project, which Labor also opposes.

Opposition Leader Daniel Andrews refused to say if he would move a motion stopping the government from signing contracts before the November 29 election.

"We'll continue our fight and I'm sure you'll understand that I'm not necessarily going to be laying out everything that we might do," Mr Andrews told reporters on Friday.

"Denis Napthine should not sign these contracts and I'm not going to wave him through."

Mr Andrews has said Labor would honour any contract signed before the election, but now has the power to block the government from doing so.

Mr Shaw last week said the East West Link should be taken to an election and described the money involved as "ludicrous".

The Liberal-turned-independent MP survived the second attempt to kick him out of parliament on Thursday after he voted with Labor against the premier's expulsion motion.

Premier Denis Napthine says the government will get on with its job, with or without the support of Mr Shaw.

Dr Napthine said parliament had abolished defensive homicide, tightened puppy farm laws and made other changes the same week he attempted to expel Mr Shaw for contempt of parliament.

"This week he's been in the house all week and we've passed five very, very important pieces of legislation," Dr Napthine told Fairfax Radio.

"We'll continue to put forward important pieces of legislation.

"We expect all members of parliament to debate them and support them."

Dr Napthine said his move to expel the Frankston MP, after he labelled his own apology to the parliament for misusing his entitlements a farce, was consistent with the government's position when Mr Shaw was suspended in June.

"Our government has followed a logical, consistent process and Geoff Shaw failed the test and therefore he should have been held in contempt and thrown out of parliament," Dr Napthine said.

Mr Shaw said the premier was acting erratically over comments in a newspaper.

"He wants to pick on and bully the one and use all the tricks and all the shady stuff in parliament to be able to try to expel me," Mr Shaw told reporters on Thursday.
