A prominent Iranian lawmaker has denounced the Supreme Court’s partial reinstatement of President Trump’s travel ban, claiming that it’s an “obvious breach” of the 2015 nuclear deal between Tehran and world powers, including the United States.

Hossein Naghavi Hosseini, spokesman of the parliament’s committee on national security and foreign policy, says the ban’s reinstatement is “a new restriction in the post-nuclear-deal era that is considered an obvious breach of the deal.”

Hosseini claimed that under the nuclear deal, countries that signed it are prohibited from imposing new restrictions or sanctions on Iranians. But he did not explain how that is connected or relevant to the travel ban.

The Supreme Court on Monday said it will allow Trump to forge ahead with a limited version of his ban on travel from six mostly Muslim countries to the U.S. Trump hailed the decision as a “victory for national security,” but it’s likely to set off a new round of court disputes over anti-terror efforts and religious discrimination.

The justices will hear full arguments in October in the case, which has stirred heated emotions across the nation and pointed rebukes from lower courts saying the administration is targeting Muslims. Until then, the court said Monday, Trump’s ban on visitors from Iran, Libya, Somalia, Sudan, Syria and Yemen can be enforced if those visitors lack a “credible claim of a bona fide relationship with a person or entity in the United States.”

The ban is to be implemented 72 hours after being cleared by courts, which means it will take effect Thursday morning.

Hosseini’s remarks were carried by the official IRNA news agency on Tuesday.
