Contracts for personal service raise a special problem, courts will not force someone to actually work for another party, but that does not mean such contracts are toothless. When the agreement also contains a promise not to work elsewhere, equity steps in through the negative covenant. This is the reasoning that decides the present case.
The negative promise stands on its own footing from the positive one, and it is this negative promise that the court will protect through an injunction.
Four possible outcomes are offered for this dispute, and testing each against the settled position on personal-service contracts under the Specific Relief Act, 1963 quickly narrows the field to one.
Ruling out blanket refusal, compelled performance, and damages-only relief leaves the negative-covenant injunction as the sound outcome.
Hence, the correct answer is The injunction may be granted to enforce the negative covenant.
