A group of lawyers are suing the Climate Minister - suggesting the Government's emissions reduction plan doesn't go far enough.

They want a judicial review over the coalition's cancelling of policies from the plan set in place by the previous Government. 

Climate consultant Dr Christina Hood says if the group is successful, the court can order the Government to rethink the current scheme.

"There was a judicial review about the emissions trading scheme a couple of years ago - the High Court, in that case told the Government to go back and have another think and the Government did that."
