When Supilo drew up the Rijeka Resolution hoping to draw anti-Austrian Hungarians to his cause, the empire's authorities provided the publicist H. Friedjung with documents alleging that Supilo and his associates were working on behalf of Serbia.
Supilo sued Friedjung and the trial of 1909 demonstrated that the documents were forgeries.
