​Victoria's planning tribunal should be "reined in" or stripped of its powers after it approved another huge tower complex for the St Kilda Junction, says a Port Phillip councillor.

At 26 storeys, the twin apartment development One St Kilda Junction will be the largest yet for St Kilda's gateway road intersection.

Two towers are set to constructed at the messy meeting point of St Kilda Road, Punt Road and Wellington Street (one 43 metres high, the other about 96 metres high). The buildings will be joined by a sky bridge.

Port Phillip Council is seeking legal advice over whether to appeal the decision at the Supreme Court.
