Where is the measure of what is permissible? And who measures it?

The measure of what is permissible is ultimately determined by the law, as it is the legal system that sets out the boundaries of what is and is not allowed. This is done through the process of legislation, in which elected representatives create laws that define what is permissible and what is not. In addition, the courts play an important role in interpreting and applying the law to specific cases, and in doing so, determining what is permissible.

In some cases, there may be some ambiguity as to what is permissible and what is not. In such cases, the courts are tasked with determining what is permissible based on the facts of the case and the law that applies. This is done through the process of judicial review, whereby the court reviews the facts of the case and the applicable law and then makes a decision as to whether the action in question is permissible or not.

Ultimately, the law and the courts are the ones who measure what is permissible. They are the ones who set the boundaries and make the final determination as to what is and is not allowed.
