Lawyers are not the only ones making the case "for" or "against" Obamacare. The voices of the American people are growing louder too.
People began lining up outside the United States Supreme Court three days before the historic health care hearings began.
The line is just one indicator of how much Americans across the country are concerned about what the judges will decide to do with President Obama's controversial healthcare overhaul.
Julie Craig has watched the two-year battle from Virginia Beach, Va.
"It's becoming a socialist country," Craig told CBN News.
"It's government healthcare instead of the people's individual benefits. I mean the price is going to rise. And we are going to end up in worse shape than what we are now," she said.
Some polls shows support for repealing the president's healthcare plan is at its highest in eight months. One Rasmussen survey shows 56 percent of voters support repealing the plan, while only 39 percent oppose it.
Del Karlesen is among the 39 percent who oppose a repeal. Still, even some supporters of Obamacare admit they understand the growing concern about the law's insurance mandate.
It says Americans who do not purchase insurance by 2014 will have to pay a penalty.
"Probably their thoughts are, if the government can say people have to buy insurance, then they can also force people to purchase other things," Debra Waterbury, an "Obamacare" opponent, reasoned.
That is what's most troubling for Patrick Connor from the National Federation of Independent Businesses.
"Where in the Constitution do they give Congress the authority to dictate to any of our members -- to any individual in America -- to buy a product from some private company?" Connor asked.
Following the three days of hearings, a decision from the high court is not expected until June.
But Waterbury is already worried about what happens if the justices rule to repeal the law.
"I have a son who has a chronic health condition and has difficulty now getting insurance because of that," Waterbury said. "And also I have numerous friends who are single and have problems and can't afford health care themselves."
