Maryland Statutes
Part III - Restrictions on Injunctive Relief
Section 4-314 - Temporary and Permanent Injunctions

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.
