What is Final Disposition?

Legal Definition
When it is said to be essential to the validity of an award that it should make a "final disposition" of the matters embraced in the submission, this term means such a disposition that nothing further remains to fix the rights and obligations of the parties, and no further controversy or litigation is required or can arise on the matter. It is such an award that the party against whom it is made can perform or pay it without any further ascertainment of rights or duties. Colcord v. Fletcher, 50 Me. 401.
