The Yanus Protocol is collection of laws by the Church of Titanius that primarily concerning regulating relations and interactions between ecclesiastical and secular authorities, ecclesiastical and secular laws. The Yanus Protocol was first signed in the Kingdom of Froturn at an unknown time (see further in History), and since that time, the rulers of the Kingdom of Etrand and the Principality of Artaburro have joined in following the Yanus Protocol.

Laws
The Yanus Protocol primarily defines the norms of interaction between religious and secular authorities, and proclaims the procedures that need to be followed in event of conflicts of interest:
 * If a Titanius-following subject of a sovereign who has vowed to uphold the protocol commits to an action that is criminalized by Church laws but not secular laws, he or she is to be punished according to Church laws.
 * The Sovereign has the right to veto the verdict the Church has given.
 * The Sovereign enjoys immunity to corporeal sanctions from the Church such as imprisonment or execution, but may be still subject to non-corporeal sanctions from the Church, such as fines or obligations to undo an edict. Failure to comply with Church orders may lead to excommunication.
 * The Sovereign has the right to grant immunity to any subject of his or her state, but the given person may only enjoy that immunity while residing in that state.
 * If a Titanius-following subject of a sovereign who has vowed to uphold the protocol commits to an action that is criminalized by secular laws but not by Church laws, he or she is to be punished according to secular laws.
 * The Hierophant has the right to veto the verdict the secular authorities have given, but only under the condition that the accused is to be placed under Church protection (essentially house arrest within facilities owned by the Church) or exiled from the state that wishes to punish the aforementioned individual.
 * The Hierophant enjoys immunity to both personal punishment and any other types of sanctions from all secular authorities.
 * The Hierophant has the right to grant immunity to any Titanius-following individual, but the given person may only enjoy that immunity while absent from the country that wishes to punish the aforementioned individual or under Church protection.
 * When Church laws and secular laws conflict in the criminalization of an action - such as a conflict in the magnitude of punishment for the crime, or one of the two specifically defines the act as not a crime - the two sides are required to make a compromise.
