A more thorough explanation:

Leguleian

A leguleian is a type of lawyer who is known for being petty and argumentative. They often focus on small details and technicalities rather than the bigger picture. The term can also be used as an adjective to describe someone who acts in this way.

• During the trial, the leguleian lawyer spent hours arguing over a minor point that had little relevance to the case as a whole.
• His leguleian approach to negotiations made it difficult to reach a compromise.

These examples show how a leguleian lawyer can be overly focused on small details and technicalities, rather than the bigger picture or the overall goal of the case or negotiation.
