The co-founder of health-care coverage advocacy group Get America Covered argues that if the Supreme Court upholds a federal judge’s decision to strike down the Affordable Care Act (ACA), it would hurt “every single American,” and have a potentially “catastrophic” effect on those protected under the landmark health-care law.

“If the Supreme Court does uphold this decision, which I don’t think is crazy to think that they could, what would that mean for consumers?” Hill.TV’s Krystal Ball asked Joshua Peck during an interview on Monday.

“Every single person in America would be hurt if this decision were upheld,” the former chief marketing officer for Healthcare.gov said.

Peck estimates that 133 million people with preexisting conditions that are protected under ACA— or ObamaCare — would no longer be protected from discrimination if the Supreme Court sides with the federal judge. As a result, he said women could be charged more than men for health-care coverage, those with contraceptive coverage could lose it and 18- to 26 year-olds may no longer be covered under their parent’s plan if the judge’s decision is upheld.

“The list of things — of benefits and protections — that people would lose is so long that I can’t remember all of them, so if this decision were upheld, it would be catastrophic,” Peck told Hill.TV.

U.S. District Court Judge Reed O'Connor on Friday ruled ObamaCare's individual coverage mandate is unconstitutional, and that because the mandate can’t be separated from the rest of the law, the federal statute cannot stand.

While the Texas judge acknowledged in his ruling that health care is a “politically charged affair,” Peck argues that the timing of the decision doesn’t seem like a coincidence, noting it came just one day before the deadline to sign up for coverage for next year.

“The practical effect of this ruling on the night before the final deadline of enrollment is confusion,” said. “Customers who were thinking about getting coverage heard the news that Affordable Care was struck down and for a lot of people that’s going to be they’re not going to sign up.”

Peck emphasized that ObamaCare will remain in effect while the case is appealed.

“It does not affect anyone who currently has coverage, the ACA is still the law, open enrollment is still happening in seven states and the District of Columbia, you can still get enrolled,” he said.
