The Legislature is asking the state Supreme Court to reconsider its ruling last month that an environmental impact assessment should be completed before the Hawaii Superferry can operate.

The friend-of-the-court brief was filed Thursday. Both it and another motion filed Tuesday by Gov. Linda Lingle asks the court to reverse its decision that a 2007 Hawaii law was unconstitutional because it was written to specifically benefit only one party, the Superferry.

The law, known as Act 2, allowed the Superferry to operate while a scaled-down environmental report was written.

The Legislature's brief says the ruling will hamper its ability to make policy that benefits the state, even if it knowingly or unknowingly pertains to only one person, business or other entity.
