“55 The background to the decision in Masri (No 2)[2009] QB 450 was that it had long been thought that the power in what is nowsection 37(1) of the Senior Courts Act 1981 (formerly theSupreme Court Act 1981 ) to “appoint a receiver in all cases in which it appears to the court to be just and convenient to do so” could only be exercised in circumstances which would have enabled the court to appoint a receiver prior to theSupreme Court of Judicature Act 1873 (36 & 37 Vict c 66), section 25(8) , when it was first put on a statutory basis…. 56 But in Masri (No 2)[2009] QB 450 it was held that these decisions were based on a misunderstanding of North London Railway Co v Great Northern RailwayCo(1883) 11 QBD 30 and that the court was not bound by pre-1873 practice to abstain from incremental development. The jurisdiction could be exercised to apply old principles to new situations. Masri (No 2) confirms or establishes the following principles: (1) the demands of justice are the overriding consideration in considering the scope of the jurisdiction under section 37(1) ; (2) the court has power to grant injunctions and appoint receivers in circumstances where no injunction would have been granted or receiver appointed before 1873; (3) a receiver by way of equitable execution may be appointed over an asset whether or not the asset is presently amenable to execution at law; and (4) the jurisdiction to appoint receivers by way of equitable execution can be developed incrementally to apply old principles to new situations. 57 Masri (No 2) also confirmed that section 37(1) does not confer an unfettered power. It pointed out that there are many decisions on the injunctive power to that effect: South Carolina Insurance Co v Assurantie Maatschappij “De Zeven Provincien”
“although the terms of section 37(1) of the Act of 1981 and its predecessors are very wide, the power conferred by them has been circumscribed by judicial authority dating back many years.”… 58 So too in Masri (No 2)[2009] QB 450 it was confirmed that the power to appoint receivers under section 37(1) is also not unfettered…”
