a. Prior tempore potior iure
c. Statutory Security Rights and Priority Privileges
Cases 171–178a. Although the Roman rule of “prior in time, greater in right” is the default principle in the common law of security interests, it is often subject to statutory exceptions. For a comparison of these issues as between UCC Article 9 and German law see Hausmann, Jens. “The Value of Public-Notice Filing under Uniform Commercial Code Article 9: A Comparison with the German Legal System of Securities in Personal Property.” 25 Ga. J. Int’l & Comp. L. (1996): 427.
Cases 182–185. In U.S. jurisdictions statutory priority is generally granted to tax liens, mechanics liens, and landlord’s liens, all of which are excluded from the scope of the UCC. See UCC § 9–109 (c) and (d).
