A more thorough explanation:

Bones gents (bohn jents). [Law French “good men”] Historically, qualified or competent persons; especially, men qualified to serve on a jury.

• During the medieval times, the judge would select a group of bones gents to serve on a jury and decide the verdict of a trial.
• In modern times, the court still requires a group of bones gents to serve on a jury and determine the outcome of a case.

The examples illustrate how bones gents refer to individuals who are considered qualified or competent to serve on a jury. In the past, the term was used to describe the group of men selected by the judge to serve on a jury. Today, the court still requires a group of qualified individuals to serve on a jury and make decisions based on the evidence presented in a case.
