Norris-Thermadore Rule Law and Legal Definition

To codify its policy, the Board, in Norris-Thermador, adopted the policy that parties to a representation proceeding should be permitted definitively to resolve as between themselves issues of eligibility prior to the election if they clearly evidence their intention to do so in writing. Therefore, where parties enter into a written and signed agreement which expressly provides that issues of eligibility resolved therein shall be final and binding upon the parties, such an agreement, and only such an agreement,” is considered a final determination of the eligibility issues unless it is, in part or in whole, contrary to the Act or established Board policy. This is known as the Norris-Thermador rule since it was adopted in Norris-Thermador Corp.
