What are Maxims?
Legal maxims are general statements that are typically expressed in a standardized Latin form.
There are those that date back to early Roman law.A legal maxim is a type of aphorism and broad maxim that is an established legal principle or notion. It is a variation on the Latin maxima, but the latter word does not exist in the existing texts of Roman law with any meaning that is precisely comparable to a legal maxim in the definitions of the Middle Ages or the Modern Era.
