Judge Robert Stack rendered the decision on Friday morning. The provincial government was found not liable for moose-vehicle collisions.
"The province, of course, is glad to hear that [Stack's decision]," said Transportation and Works Minister Nick McGrath.
"We felt that we put up a strong case in the courts and obviously the judge felt the same, so we were pleased to hear that the case has been dismissed and taken out of the courts."
St. John's lawyer Ches Crosbie launched the class-action lawsuit in January 2011, claiming the provincial government is to blame for failing to control the moose population.
McGrath added the province is "committed to mitigating," as many moose-vehicle collisions as possible.
The decision comes on the same day the provincial government admitted the Trans-Canada Highway moose sensor pilot project didn't work as planned.
The sensors were installed in July 2011, but McGrath said they were working only about 40 per cent of the time.
McGrath said his department is in the process of putting together a presentation on the pilot project for government to decide how to move forward.
