A more thorough explanation:

Definition: Temere jurantes super assisam (tem-uh-ree juur-an-teez soo-puhr uh-sI-zuhm) is a Latin legal term that refers to persons who swear rashly upon an assize.

Example: In medieval England, jurors who were afraid of the consequences of their verdict would sometimes commit temere jurantes super assisam by swearing falsely on the Bible.

Definition: Temerarium perjurium super assisam (tem-uh-rair-ee-uhm puhr-juur-ee-uhm soo-puhr uh-sI-zuhm) is a Latin legal term that refers to the act of committing rash perjury on an assize.

Example: If a jury returned a perverse verdict, it was said to be the result of temerarium perjurium super assisam, meaning that the jurors had lied under oath in order to reach their decision.

Explanation: These two related terms describe the act of swearing falsely on an assize, which was a legal proceeding in medieval England. Jurors who committed temere jurantes super assisam would swear rashly on the Bible, while those who committed temerarium perjurium super assisam would lie under oath in order to reach a perverse verdict. These terms illustrate the importance of honesty and integrity in the legal system, and the consequences that can result when jurors fail to uphold these values.
