A more thorough explanation:

A conversionary act is a voluntary deed or action that makes the actor liable for conversion, unless it is privileged. Conversion is a tort that occurs when someone wrongfully takes or uses someone else's property without permission.

Examples of conversionary acts include:

• Taking someone else's car without their permission
• Selling someone else's belongings without their consent
• Using someone else's trademark without their authorization

These examples illustrate how a conversionary act can result in liability for the actor who wrongfully takes or uses someone else's property. It is important to obtain permission or authorization before using or taking someone else's property to avoid liability for conversion.
