Ethicist: In a recent judicial decision, a contractor was ordered to make restitution to a company because of a bungled construction job, even though the company had signed a written agreement prior to entering into the contract that the contractor would not be financially liable should the task not be adequately performed.
Conclusion
It was morally wrong for the company to change its mind and seek restitution from the contractor.
Evidence
Before the contract, the company had signed a written agreement that the contractor would not be financially liable for inadequate performance. Despite this, a court ordered the contractor to make restitution.
Evaluate
The ethicist concludes a moral judgment from the fact that the company had previously waived the right to seek financial liability. The argument needs a principle that ties "promised not to seek compensation" to "morally wrong to seek compensation."
Goal
The correct answer should state a principle that, when applied to these facts, generates the conclusion that seeking restitution after promising not to is morally wrong.
