A more thorough explanation:

Non ponendis in assisis et juratis (non pəˈnɛndɪs ɪn əˈsʌɪzɪs ɛt dʒʊˈreɪtɪs), n. [Law Latin “not to be put in assizes and juries”] is a historical writ that discharges a person from jury duty.

During medieval times, it was common for people to be summoned for jury duty. However, some individuals were exempt from serving on a jury. For instance, clergymen were not required to serve on a jury because they were considered to be representatives of the church. Similarly, the writ of non ponendis in assisis et juratis could be used to excuse someone from jury duty if they had a valid reason, such as being too ill to serve.

For example, if a person was summoned for jury duty but had a medical condition that made it difficult for them to sit for long periods of time, they could request a writ of non ponendis in assisis et juratis to be excused from serving on the jury.

Another example would be if a person was a close relative of one of the parties involved in the trial. In such a case, the person could be excused from serving on the jury to avoid any potential bias.

These examples illustrate how the writ of non ponendis in assisis et juratis was used to exempt individuals from serving on a jury for various reasons.
