The British withdrawal fromthe EU has forced the redefinition of the European statuteof Gibraltar, and its relations with Spain and the EuropeanUnion, in institutional, legal and economic terms. In thiscontext, novel mechanisms have also been devisedto regulate the treatment of cross-border cooperationwith Gibraltar, which has had intermittent phases in itsevolution over time. Within the framework of the Britishexit process, a new model has been agreed in successiveEU-UK agreements that combine Hard Law (Primary EULaw) with Soft Law (Memoranda of Understanding–MOU).This regulation has required a specific prior BritishSpanish negotiation.We will especially highlight the UK-EU Withdrawal Treatyof 2019, which has formed an authentic system of crossborder cooperation involving the UK, the EU, Gibraltarand Spain, through a series of Spanish-British bilateralMemoranda interconnected with the Protocol on Gibraltarof the Treaty, which in turn refers to the Tax Treaty.
