In 1908, the Coalition won the election again, but it also came under attack from the Vienna Imperial Court, which accused its leadership of grand treason. In 1909, 53 members of the Serb Independent Party were put on trial for collaboration with Serbia. In this politically motivated trial, known as the Agram Trial, the defendants were found guilty with flimsy evidence and given prison sentences. As the international political situation shifted (the Serbian government recognized Austria-Hungary's annexation of Bosnia-Herzegovina), the members were pardoned by Franz Joseph in 1910. This came at a cost of having to marginalize their leader Frano Supilo and having to temper their criticism of the government in the Kingdom of Hungary. Svetozar Pribićević became the new leader and closed a formal agreement with the government in 1913. The Coalition continued to win elections in 1910 and 1913. It dominated Croatian South Slavic politics throughout World War I. While the leaders of the Coalition continued to participate in Austro-Hungarian politics, they also participated in the Yugoslav Committee during World War I.
