Explain why the determination of the performance of a contract cannot be left to one of the part

Determination of Performance by Third Person As a rule, compliance with a contract cannot be left to the will of one of the contracting parties. However, the determination of its performance may be left to a third person after it has been made known to both contracting parties. Provided, further, the parties are not bound by the determination if it is evidently inequitable or unjust when the third person acted in bad faith or by mistake, the courts shall decide what is equitable under the circumstances. Example, Gaya sold her parcel of land to Laura. It was agreed that Maya, a real estate appraiser would be the one to determine the reasonable price of the land. Maya, then, fixed the price after considering the factors affecting the value of the land, and informing both contracting party that the decision is just and suitable. If the decision made by Maya is manifestly inequitable, the court may be called upon to decide what is equitable
