The DNC claims Russian persons hacked one of their servers and leaked emails to WikiLeaks and Guccifer 2.0, purportedly operating at the behest of the Russian state, which was claimed to be seeking a Trump presidency.
"By transmitting this letter and the enclosed Statement, the Russian Federation respectfully does not enter an appearance in the litigation, does not waive its sovereign immunity under international law or the United States, statutory or federal common law, and does not submit to the jurisdiction of the United States District Court," the document said on Friday.
The US District Court lacks subject-matter jurisdiction under the Foreign Sovereign Immunities Act (FSIA) to hear claims against the Russian Federation based on the DNC's allegations, the document said.
The document also said the US District Court should reject the DNC's efforts to distort the meaning of the existing FSIA exceptions and also reject the judiciary becoming involved in this "fundamentally political and diplomatic issue."
