Odofredus (1250) to Cod. 7.37.3 (Bene a Zenone) (Lyon: 1480), vol. 1, unfol.: "Here Martinus wished to state that the emperor is the lord of all property.  He cited a law that asserted that the emperor can give property to the soldiers in the army.  .   .  . But we say otherwise, because anyone has the right to vindicate his property in court .  .  . the emperor cannot vindicate my property in court .  .  .

Guido of Suzara (1290) Suppletiones to Dig. 1.3.31(30) (Princeps legibus), Clm 6201, fol. 10v:  What if the prince makes a contract with a subject, is he held to honor the contract if he is summoned to court?  It seems that he is not bound to observe a summons since he is "legibus solutus."  .  .  .  Nevertheless, the prince is bound to honor a contract because a contract is a part of the ius gentium.  The prince cannot derogate  that right,  since the right is immutable.

Guido of Suzara (1290) to Cod. 1.14(17).4 (Digna vox), Paris, B.N. lat. 4489, fol. 33v:  Note that if the emperor makes peace with any city or with any count or baron, and enters into any agreements, he is bound to observe them; he cannot contravene nor break them .  .  . He also cannot break agreements that his predecessors made .  .  . The maxim, an equal cannot have authority does not apply in this case  .  .  . because the emperor does not have an equal as long as he lives, and a successor, his own heir, has to preserve the arrangements of his predecessors.

Johannes Bassianus (1150): "I think and believe that no rescript is of any moment that is contrary to the law of the Gospels, what we call natural and divine law, as if for example it would be granted to you <the right> to kill someone."
