An early threat to the conference was from steamers involved in the
triangular trade: outward to Australia, a second leg, usually carrying New South Wales coal, to China, then tea back to Britain. This overcame a problem with low outward rates to China (and also the shortages of cargoes back from Australia for much of the year). It was a commercial strategy that had been employed by some of the later tea clippers, such as the
Aberdeen Line's
Thermopylae. Steamers, which could make two round trips a year, were able to alternate between homeward trips from Australia, with wool, and China, carrying tea. This was more profitable than simply sailing to and from China. The shipbrokers Gellatly moved into ship owning in 1883 with the formation of the Mogul Steamship Company and operated ships on this triangular route. The Aberdeen Line's first (and highly fuel efficient) steamer started on this route in 1882. Swire challenged Gellatly over their undercutting of conference rates in 1882 at a meeting in 1885 when Mogul were seeking, unsuccessfully, to charter two ships through the conference. Gellatly responded with a threat that if his company did not have access to the conference, three Mogul steamers,
Aberdeen and others would sail to
Hankou to undercut the conference rates. Gellatly expressed the view that whilst this would cost him some thousands of pounds, the conference members' losses would be substantially greater. Gellatly's threat was carried out, with Mogul's
Pathan and
Afghan, together with
Aberdeen, loading full cargoes of tea at 25 shillings (£) per ton in June 1885. Conference ships (other than the express steamers taking the first of the crop) loaded at between 45 shillings (£) and 30 shillings (£). The conference agents in China, in May 1885, had reminded shippers of the conference terms that would cause them to lose their 5% rebate if they used non-conference ships. The result of this was that Gellatly tried to take out an injunction against the conference in August. When this failed, in 1887 he went to the
High Court, alleging that the conference was seeking to prevent Mogul from trading. Gellatly did not succeed, so he took the case to the
Court of Appeal, where he lost again. He then went to the highest court of appeal, the
House of Lords, losing his case for the third time in December 1891. Gellatly and the Mogul Steamship Company somehow ended their dispute with the conference and became members again. The Aberdeen Line ceased to sail to China after 1889 and concentrated on trade to and from Australia, with some added stops in Cape Town. ==Further challenges==
