Which legal measure is used by agencies to stop violations?

The correct answer is the cease and desist order. This legal measure is specifically designed to prohibit a party from continuing an action that violates the law or regulations. Regulatory agencies utilize cease and desist orders when they identify illegal activities that need to be halted immediately to protect public interests or prevent further violations.

Cease and desist orders are effective because they compel the violator to stop the infringing conduct and can also set the stage for further legal actions or penalties. They serve both as a preventive measure, ensuring that the violation does not continue, and as a way to formally notify the offending party of the alleged violation.

Agencies often prefer this approach because it can be issued quickly and provides a clear directive that must be followed, thus helping to maintain compliance with relevant laws and regulations.
