Canton Trading, a firm of architects, provided professional architectural services to the Qwaha Trust for several projects since 2011. In 2013-2014, Canton Trading was engaged for a project to expand the Itau Mill. On 5 February 2014, Canton Trading, as principal agent for the Trust, concluded a JBCC building agreement with a contractor. In March 2014, Canton Trading's attorneys prepared a document titled 'Appointment of Professional Service Provider' (PSP), which contained an arbitration clause (clause 23) referring disputes to mediation and arbitration under AFSA rules. The PSP was never signed by either party, but Canton Trading rendered services and was paid by the Trust. The JBCC agreement was terminated on 2 August 2014 due to defective work by the contractor. The Trust alleged Canton Trading failed in its duties and in 2017 invoked the arbitration clause in the PSP. After correspondence, Canton Trading initially agreed "in principle" to arbitration and to appointment of an arbitrator. However, at a pre-arbitration meeting on 24 January 2018, Canton Trading requested insertion of a clause requiring its insurer's consent. Shortly thereafter, on 30 January 2018, Canton Trading took the position that the PSP was never signed and the arbitration clause was unenforceable. The Trust applied to the high court to compel Canton Trading to submit to arbitration.
