Public trust doctrine

Explanation:

The Public Trust Doctrine is English law that allows people to cross private land to follow rights of way.

This doctrine allows people to use some privately owned resources when rights of way need to be secured. This doctrine can be used, for example, on the shoreline between the high and low tides, when citizens need to cross these places, or when public use of private land in that region is required.
