Similar case happened in Vancouver this winter. Some skiers deliberately left a ski resort to ski back-country.
The ski patrol attempted to stop them and when they refused to return to the resort they initiated a rescue effort.

The skiers were eventually caught, they claimed that they were not in danger (a couple were avalanche instructors) and that they had a right to be on the land (crown land = government owned, open access but not a national park). This lead to a tricky situation since the rescue agency doesn't have powers of arrest but can force people to be rescued for their own safety. The resort banned them and fined them $15,000 as the cost of the rescue.

There are allegations that the resort is using this to effectively privatise the surrounding mountains, if they can force a 'rescue' and huge fine on anyone that doesn't stay within their property.

Developments with expensive beach front homes could also use it as a way of restricting entry to the public beach by threatening the public with huge rescue costs for anyone entering the water.
