ST. JOHN'S, N.L. -- A Newfoundland man's court challenge of the Muskrat Falls hydroelectric project got off to a rough start after the judge refused to hear one of his main arguments.

Judge Gillian Butler said Brad Cabana should have sent the federal Attorney General a copy of his statement of claim.

It alleges various constitutional violations he asserts should halt the $7.7-billion development in Labrador.

At issue are changes to the provincial Electrical Power Control Act, and a subsequent water management agreement.

The political blogger and small businessman says they violate Hydro-Quebec's contracted water flow rights on the Churchill River.

He asked for a 10-day delay to file the required documents, but Butler ultimately dismissed Cabana's request.

Cabana is trying to stop construction of the dam and power station near Happy Valley-Goose Bay that started last year.

Both the government and Nalcor Energy say his claims are without merit.
