Where a plaintiff is entitled to choose as the forum a court exercising federal jurisdiction, and the defendant is within Australia, he is amenable to the command of the federal writ in whatever part of Australia he is served. The body of law to be applied, however, is the law of the place in which the court exercises its jurisdiction (Judiciary Act 1903 Cth, s. 79). The body of general law which binds such a court speaks, as it were, with a variety of tongues, and a federal court when it chooses its venue determines the tongue to which it will listen. In making the choice, the rules of private international law provide no binding guidance, for the choice of law follows inexorably from the place where the jurisdiction is exercised. A similar problem arises when this Court exercises a discretion to remit an action for trial by a Supreme Court of a State or Territory: the choice of the court to which the action is remitted determines the body of law which is to be applied to it. Where the action is a claim for damages in tort, there are powerful reasons for adopting the law of the place where the tort is committed. If it were not for the existence of an obligation under that law, no cause of action would be enforceable under any other body of law which might be made applicable to the resolution of the matter. The law of the place where the tort was committed is the law which first gives rise to the cause of action, and it is material that the courts of a State or Territory other than the State or Territory in which the tort was committed would not have jurisdiction unless the defendant were served within the State or Territory or unless he entered an unconditional appearance, for the plaintiff could not otherwise make the defendant amenable to that Court's jurisdiction: cf. Weber v. Aidone [6] and Guzowski v. Cook [7] .
