On 12 October 2001, SGS filed a Request for Arbitration with ICSID against Pakistan for violations of the Switzerland–Pakistan Bilateral Investment Treaty (BIT) and the PSI Agreement. On 4 January 2002, SGS sought an injunction against the Pakistan Arbitration in the Pakistani courts. SGS’s application wasrejected at various lower court levels until the matter finally reached the Supreme Court of Pakistan. On 3 July 2002, the Supreme Court granted Pakistan’s request to proceed with the Pakistan Arbitration and restrained SGS from participating in the ICSID arbitration. e Supreme Court of Pakistan noted that the Switzerland–Pakistan BIT had no legal effect under Pakistani law because it had not been implemented into municipal law and that the parties’ contractual agreement to arbitrate in Pakistan should be enforced. Notwithstanding that decision of the Pakistani Supreme Court, the ICSID Tribunal (“the Tribunal”) decided to proceed with hearing the matter. On 12 November 2002, the sole arbitrator in the Pakistan Arbitration agreed to stay proceedings until the Tribunal determined whether it had jurisdiction to consider SGS’s claims
