A more thorough explanation:

nisi prius roll

A document that contains the written record of a court case that was heard at nisi prius, which is a lower court that hears cases before they are appealed to a higher court. It is also known as a nisi prius record.

An example of a nisi prius roll would be the written record of a personal injury case that was heard in a district court before it was appealed to a higher court. The roll would contain a transcript of the testimony given by witnesses, the arguments made by the lawyers, and the judge's ruling.

Another example would be the written record of a contract dispute that was heard in a county court before it was appealed to a state court. The roll would contain a transcript of the evidence presented by both parties, the legal arguments made by their lawyers, and the judge's decision.

The examples illustrate how a nisi prius roll is a written record of a court case that was heard in a lower court before it was appealed to a higher court. The roll contains a transcript of the proceedings, including the testimony of witnesses, the arguments made by lawyers, and the judge's ruling. This document is important because it provides a record of what happened in the case, which can be used to support an appeal or to review the decision made by the lower court.
