A more thorough explanation:

Definition: Apertum factum is a Latin term that means "open deed." It refers to an overt act, which is an action that is done openly and without any attempt to hide it.

Examples:

• When John signed the contract, it was an apertum factum that he agreed to the terms.
• By publicly announcing his candidacy, the politician made an apertum factum that he was running for office.
• When the company released its financial statements, it was an apertum factum that they were profitable.

These examples illustrate how apertum factum refers to an action that is done openly and without any attempt to hide it. In each case, the action was clear and obvious, leaving no room for doubt or interpretation.
