Maryland § 4-314

§ 4-314.

    In addition to any other limitation under this Part III of this subtitle, a court may not issue a temporary or permanent injunction in a case that involves or grows out of a labor dispute unless:

        (1)    each known person against whom relief is sought and each public officer who has a duty to protect the property of the plaintiff is given, in the manner that the court directs, personal notice that the court will hold a hearing on issuance of a temporary or permanent injunction;

        (2)    at the hearing, the court takes, in open court, testimony offered against the temporary or permanent injunction and affords the opportunity for cross-examination; and

        (3)    as a result of the hearing, the court finds that:

            (i)    an unlawful act:

                1.    has been threatened and, unless restrained, will be committed; or

                2.    has been committed and, unless restrained, will be continued;

            (ii)    unless it grants the relief requested, the property of the plaintiff will be injured substantially and irreparably;

            (iii)    greater injury will be inflicted on the plaintiff for each item of relief that the court denies than will be inflicted on the defendant if the court grants the item;

            (iv)    it is not granting any item of relief for which a court lacks jurisdiction under § 4-307 of this subtitle;

            (v)    the plaintiff has no adequate remedy at law; and

            (vi)    each public officer who has a duty to protect the property of the plaintiff has failed or is unable to give adequate protection.
