Which of the following is NOT a method of resolving disputes between partners?

The method of resolving disputes between partners that is not recognized as an official method in the context of partner disputes is the sole decision by the majority partner. While it's common for partnership agreements to specify how decisions should be made, relying solely on the majority partner to make decisions can lead to a lack of fairness and can undermine the collaborative nature of partnerships.

Negotiation, mediation, and arbitration are all established methods for conflict resolution. Negotiation involves the parties discussing their issues directly to reach an agreement. Mediation introduces a neutral third party to help facilitate a resolution, while arbitration involves a third party making binding decisions to resolve the dispute. These methods promote dialogue and encourage resolution based on mutual agreement or external guidance, which is essential in maintaining productive partnerships. In contrast, allowing one partner to make unilateral decisions disregards the collaborative agreement inherent in a partnership structure and can result in discord among partners.
