A continual usage is of great effect to establish a right.

Explanation

(English-origin maxim.) Long and uninterrupted exercise of a right is powerful evidence of its existence — cite this to establish prescriptive rights, customary easements, or longstanding community practices as legally binding.

Where this applies

• A family has walked across a neighbor's field every day for sixty years to reach the river, and the court recognizes a prescriptive easement because the continuous use powerfully establishes the right.
• A community has held a market on a particular town square every Saturday for over a century, and the court holds the longstanding custom has the force of law establishing the community's right to use the space.
• A church has rung its bells at noon every day for two hundred years, and when a new neighbor complains of noise, the court finds the continuous usage establishes a right that cannot be taken away.
