"Iran must not be permitted to continue to misuse the International Court of Justice’s judicial process for political and propaganda purposes", State Department Deputy Spokesman Robert Palladino said on Wednesday.
Earlier in the day, the International Court of Justice ruled that Iran's lawsuit against the United States over more than $2 billion in frozen assets was admissible.
Palladino said the case is yet another example of how Iran seeks to misuse legal processes and distort principles of international law.
The US Supreme Court ruled in 2016 that the money frozen by the United States should go to the survivors and families of victims of terrorist attacks attributed to Iran. Tehran claims that this decision violated the 1955 US-Iranian Treaty of Amity.
Washington said last October that it was terminating the treaty after the International Court of Justice ruled the United States breached the agreement by re-imposing sanctions linked to Tehran's nuclear program.
