Ad intelligentiam sequendorum premittendum quoddam indubitatum, uidelicet quod princeps Romanus potest sua castra et iurisdictiones et dignitates in feudum assignare et conferre. Et tanta est in eo plenitudo potestatis quod legibus solutus est ut ff. de legibus l. Princeps. Et licet de plenitudine honestatis teneatur habere firmas concessiones suas et non debeat uenire contra fidem precessorum suorum quia debet esse cultor et auctor iusticie, ut in c. Si clientulus  § Ecclesia et in c.i. de natura feudi, ubi dicit quod non potest disuestire sine causa quia fides est de iure naturali, tamen si aliquod motiuum ---  etiam leue --- mouet principem, de plenitudine potestatis facere potest, quod ei libet, iuxta illud antiquum uerbum, si libet, licet, ut dicta l. Princeps et C. eodem l. Digna uox  ---- To understand the following we must establish the indisputable: the Roman prince can bestow and confer his fortresses, jurisdictions, and dignities as fiefs.  So great is his fullness of power that he is legibus solutus.  Although by fullness of honesty he is held to maintain his grants and not contravene the promises of his predecessors, it is because he is the cultivator and author of justice.  Although the Liber feudorum states that the prince cannot strip anyone of his fief because an oath is an institution of natural law, nevertheless if the prince is moved by a reason, even a minor reason, he can strip someone of his fief from his fullness of power because it pleases him, according to Digna vox, if it pleases him, it is licit.
