Against good morals. It is a matter of controversy to what extent the criminal law should, or does, prohibit immoral conduct merely on the ground of its immorality. The tendency in recent years has been to limit legal intervention in matters of morals to acts that cause harm to others. However, there are still certain offences regarded as essentially immoral (e.g. incest). There are also offences of conspiring to corrupt public morals (although corruption of public morals is not in itself criminal) and of outraging (or conspiring to outrage) public decency, although the scope of these offences is uncertain. See also conspiracy.
