In a recent decision issued by the Tribunal of Milan, an order was obtained pursuant to art. 186.ter of the civil procedure code (Trib. Milan, 5 December 2017, n. 2279, ord.) for payment of an astreinte ordered according to art. 131.2 of the IP Code forfailure to comply with a restraining order antecausam in a case relating to trademark infringement.The particular interest, with respect to the institution of uncertain effectiveness such as an astreinte, lies in the procedural instrument: the Judge considered that the payment of a sum determined on a mere mathematical calculation thedetails of which are identified (a specific amount due for every day of delay)may be enjoined like the one already determined.This has allowed to obtain the partial repair of adamage suffered due to the continuance of an unlawful act which has already been enjoined as an infringement without any further steps and challenges and herefore very quickly.
