Answer:
binding arbitration
Step-by-step explanation:
Both parties agree to be bound by the decision of the arbiter and follow the recommendations/obligations stipulated by the arbiter at the end of the process.
That bound of the two parties makes it a binding arbitration.
As opposed to a non-binding arbitration where the result cannot be enforced onto the parties, a bit like a mediation. The result is more like a discussion starting point towards a negotiation of the end of the conflict.
