On Thursday morning, a Calgary judge dismissed an application from the Castle-Crown Wilderness Coalition.

It was arguing that a logging licence and a notice of development posted in the Crowsnest area last January were invalid for technical reasons.

But Justice Sandy Parker threw out the case, saying the time frame to challenge the licence has expired.

He left the door open for the group to try again if another notice of logging is posted.

Spokesperson Gordon Petersen says they will be back.

"There's no doubt that the logging will proceed this year so we'll need to get the documents that indicate and show that the logging will proceed," Petersen said.

The provincial government has suspended logging operations for the following two years in order to review logging in the sensitive area.

Activists say the Castle area in southwest Alberta is a key grizzly habitat and vital for the South Saskatchewan River watershed.
