The court will hold four separate hearings on Monday through Wednesday to take up several issues related to the law.

The biggest issue for the high court is the individual mandate, a requirement for most people to buy health insurance.

Suthers argues it sets a dangerous precedent.

"If they can order you to buy health insurance and fine you if you don't, they can order you to buy a health club membership and fine you if you don't," Suthers said.

Several viewers reached out to 9NEWS to share that sentiment, but others expressed concerns about what would happen if the law were struck down.

"What happens to those of us, who because of the healthcare bill were finally able to obtain insurance with previous existing conditions," Kim Coffey asked on the 9NEWS Facebook page. "Do we now, once again, find ourselves without any options whatsoever if it gets repealed? This bill saved my life!"

"If [the health care law] gets repealed they're going to have to go back to square one and design an insurance system," Suthers said. "My guess is it would be more of a state-based insurance system."

Suthers admits if his side wins, plenty of health policy issues would need to go back to the drawing board.

However, he thinks the justices should toss out the whole act, not just the mandate.

"I don't think the rest of the act works without the ability to spread the risk by forcing healthy 22-year-olds to buy health insurance," Suthers said.

When pressed about the fact he's fighting the provisions forcing people to buy insurance, Suthers replied: "I want 22-year-olds to buy health insurance. I don't want to give the federal government the power to force them to do it. If the state did it, I don't have a problem with that."

The Obama administration argues it does have the power under the Constitution's commerce clause, which gives Congress authority over business that crosses state lines.

The high court is not expected to hand down a decision until June.
