In the Sibur case, the Russian Supreme Court reaffirmed that if unilateral sanctions were (or are) the cause of a dispute—for example, if a contract was not performed due to the imposition of restrictive measures—then Russian arbitrazh courts (state courts) courts have exclusive jurisdiction over the matter, regardless of any arbitration clause. The dispute in that case involved bonds and included an LCIA arbitration clause (Russian Supreme Court decision dated May 30, 2025, in Case No. А40-116513/2024).
