A more thorough explanation:

Term: solutus
Definition: Solutus means to be set free or released from an obligation or confinement. In Roman law, it was used to describe someone who was no longer bound by a legal agreement or contract. In Scots law, it was used to describe a lawyer who had been cleared of any wrongdoing.
Examples:

• After serving his sentence, the prisoner was solutus and allowed to leave the jail.
• When the contract was terminated, the parties were solutus from their obligations.
• The lawyer was solutus of any charges after the court found him innocent.

The examples illustrate how solutus is used to describe someone who has been released from a legal obligation or confinement. In the first example, the prisoner was solutus from his confinement in jail. In the second example, the parties were solutus from their legal obligations after the contract was terminated. In the third example, the lawyer was solutus of any charges after being cleared of any wrongdoing.
