§ 2406 Habit - Routine practice.

If someone has a habit of doing something the same way every time, that habit can be used as evidence in court. The same goes for a business or organization that always follows the same routine. Courts allow this evidence because a strong pattern of behavior can help show what probably happened on a specific occasion.

This means you do not need an eyewitness to prove what someone did. If you can show the person or organization always acts a certain way, a judge or jury can use that pattern to conclude they likely acted the same way this time too. For example, if a company always checks IDs before serving alcohol, that routine practice can be used as proof they checked ID on the night in question, even if no one saw it happen.

It also does not matter if other evidence backs up the habit or not. The habit or routine practice can stand on its own as proof, as long as it is shown to be a regular and consistent pattern, not just something the person did once or twice.
