The third edition of this work has been completely revised to ensure an even more practical and immediately supportive tool for legal practitioners who daily find themselves filing appeals for injunctions and related oppositions. The volume, with formulary and case law, is up-to-date with all the most recent legislative changes made to the injunction appeal and opposition procedure, including Decree Law No. 59 of May 3, 2016 (conv. with amendments in Law No. 119 of June 30, 2016), on the subject of mandatory provisional enforcement of the injunction decree for uncontested amounts. The topics under analysis are: prerequisites for injunctive protection; creditor subjects and written proof; monitor judge; appeal for injunctive decree; provisional enforcement; service of injunctive decree, its effects and non-notification; opposition to injunctive decree; trial subjects and competent judge; and constitution of court; constitution of the opponent and defendant-opponent; briefing of the case and evidentiary instruction; anticipatory measures during opposition; provisional enforcement and its suspension; late opposition; rejection or partial granting of opposition; injunction in telematic form; European injunction. The text also takes into account the numerous pronouncements of the jurisprudence, of legitimacy and merit, as well as of the Constitutional Court, which over time have specified and confirmed the scope and effects of legislative innovations on the injunction procedure and the subsequent opposition phase. The enclosed CD-Rom includes a rich form, in editable and printable format, containing the outlines of the procedural acts considered most useful in the daily conduct of professional activity, an exhaustive jurisprudential review by subject and a collection of the normative provisions of reference.
