The anti-arbitration injunction is probably the most controversial institution in the history of arbitration due to its hostile interference in procedures that it pretends to terminate or suspend, and the impediment generated for the second tribunal to determine its own competence.

The existence of parallel proceedings in arbitration has posed a universal challenge to achieve predictability in every dispute settlement system across legal traditions without sufficient consensus on a common solution.

The remedies within the arbitral practice have been as radically opposed as in the judicial practice within the state courts system. In this context, two dominant positions stand out. Borrowed from the Anglo-Saxon systems -or Common Law- some arbitrators issue antiarbitration injunctions to prevent the continuation of an ongoing or potential arbitration involving a breach of the arbitration agreement or abuse of process. In contrast, in RomanGermanic systems -or Civil Law- the second adjudicator is given the opportunity to decide on its own jurisdiction in application of the non-interference principle, which is translated into the bedrock principle of competence-competence within arbitration.

In this regard, it was proven that anti-arbitration measures are an invalid way of combating the existence of parallel proceedings in light of the 1985 UNCITRAL Model Law (as amended in 2006), since it violates article 16 which empowers and limits all arbitral tribunals to rule on their own competence.
