Difference between the remedies of specific performance and injunction :

Specific performance is decreed to compel the performance of an active duty, while injunction is decreed to prevent the violation of a negative duty. Normally, the former deals with contracts, while the latter with torts and other subjects of equitable nature. If a contract is positive in its nature, it calls for the relief of specific performance, on the other hand, if it is negative in its nature, it calls for relief of injunction.

The principle governing the award of injunction as a mode of enforcement of contracts is similar to that of specific performance. This is clearly borne out by Section 38(2) of the Act. Thus, the enforcement of a contract is governed by both specific relief and injunction. “The jurisdiction of equity to grant such injunction is substantially coexistent with its jurisdiction to compel a specific performance”. But still their fields of operation are separatefrom each other. While a promise to do is enforced by specific performance, a promise to forbear is enforced by injunction. Section 41(e) further provides that contract which will not be affirmatively enforced by a decree of specific performance, will not be negatively enforced by issuing an injunction. The only exception to this rule is found in Section 42.
