Who was subjected to a "trial", in which he was formally expelled from the Surrealist group?

Salvador Domingo Felipe Jacinto Dalí i Domènech, Marqués de Dalí de Pubol (11 May 1904 – 23 January 1989), known as Salvador Dalí was a prominent Spanish surrealist painter born in Figueres, Catalonia, Spain.

While the majority of the Surrealist artists had become increasingly associated with leftist politics, Dalí maintained an ambiguous position on the subject of the proper relationship between politics and art. Leading surrealist André Breton accused Dalí of defending the "new" and "irrational" in "the Hitler phenomenon", but Dalí quickly rejected this claim, saying, "I am Hitlerian neither in fact nor intention". Dalí insisted that surrealism could exist in an apolitical context and refused to explicitly denounce fascism. Among other factors, this had landed him in trouble with his colleagues. Later in 1934, Dalí was subjected to a "trial", in which he was formally expelled from the Surrealist group. To this, Dalí retorted, "I myself am surrealism".
