Malum Prohibitum

(mal-uhm prohibit-uhm) Latin for "wrong due to being prohibited," referring to acts made illegal by statute to benefit public welfare, not because they are inherently evil and obvious violations of society's standards. Generally, they do not involve immediate injury or damage to others. Examples include violations of regulatory acts, insider trading, and tax avoidance. Compare: malum in se
