A more thorough explanation:

Definition: Byrlaw (bir-lah) is a term used in English and Scots law to refer to the local custom of a township or district for resolving disputes over boundaries, trespasses, and the use of common lands, as well as farming issues. It can also refer to a particular custom established by the common consent of landholders in a township or district. Byrlaw can also refer to the area over which a township or district court has jurisdiction. It is also spelled as burlaw.

Example 1: In a certain township, it is customary for farmers to share the use of a common land for grazing their animals. However, disputes may arise over the use of the land, and the byrlaw of the township provides a way to resolve such disputes.

Example 2: Another example of a byrlaw is the custom of a district to hold a yearly fair where farmers can sell their produce and livestock. This custom is established by the common consent of the landholders in the district.

These examples illustrate how byrlaw is a local custom that is established by the people in a particular township or district. It provides a way to resolve disputes and regulate the use of common lands and other resources. Byrlaw is an important part of English and Scots law, as it reflects the customs and traditions of the people in a particular area.
