Such injunction actions may be specifically provided for by statute. Injunction actions may also be maintained to enforce statutes which do not specifically provide for such a remedy. A preliminary injunction is an extraordinary and drastic remedy. No injunction will issue if there is an adequate remedy at law.
Irreparable injury is an essential prerequisite to the issuance of a preliminary injunction.
Temporary loss of income or other alleged injury involving only the loss of money is not irreparable injury. The injury alleged must be immediate and non-speculative. There must be a convincing showing of irreparable injury, and mere litigation expense will not suffice. Even if there will be irreparable injury, the granting of a temporary injunction is not a matter of right and may be refused in the exercise of judicial discretion. If an injunction will impair the public interest, it should be denied.
