From formation to execution, Contract Law in Oregon covers all the basics as well as the intricacies of contract law. Highlights of this 2008 supplement include updated case law on: n Enforceability of arbitration clauses. n Cognitive and affective tests for mental incompetency. An Oregon employment contract can incorporate an at-will provision, or it can alter the at-will presumption with a provision allowing termination only for good cause. In such contracts, good cause may be explicitly defined in the agreement, and bad faith, fraud, failure to use best efforts, or criminal activity may constitute good cause for termination.
