In Stutzman's case, the Washington State Supreme Court must now interpret whether she was treated fairly when the court first heard her case. Avery is also now serving a life sentence without the possibility of parole.
In this session of the Supreme Court, now drawing to a close, the justices have chose to avoid a major decision on voting rights rather than send a clear message going into the 2018 midterm elections. Dassey's attorney claims that his confession to police was coerced. News her team will "continue to fight to free Dassey".
She then appealed to the U.S. Supreme Court to hear her case.
Dassey was convicted of helping Steven Avery in the killing and mutilation of freelance photographer Teresa Halbach in Wisconsin in 2005.
Both Dassey and his uncle, now 55, were sentenced to life in prison.
Wisconsin attorney general Brad Schimel said he was "pleased" at the supreme court's decision not to appeal the conviction.
As is typical, the justices did not explain their decision declining to take the case. In its unanimous ruling, the court wrote, "Public accommodations laws do not simply guarantee access to goods or services".More news: French priest suspended after video of him slapping baby goes viral
At age 16, Dassey confessed to raping, murdering and burning Halbach's body during an interrogation by police. "Dassey's borderline to below average intellectual ability likely made him more susceptible to coercive pressures than a peer of higher intellect" and he did not have "the benefit of an adult present to look out for his interests", a court document read. She spends months or even years getting to know the bride and groom, in order to understand their vision and what they want to convey.
Wisconsin officials had urged the Supreme Court not to take the case, telling the court it shouldn't second-guess Wisconsin courts' determination that Dassey's confession was voluntary.
At the beginning of the interrogation, the state said in its brief, investigators thought of Dassey only as a witness to the crime.
"Rob was my customer and friend for over nine years", Ms. Stutzman said in a previous statement.
The Supreme Court also on Monday sent back to a lower court a North Carolina partisan gerrymandering case. The case played out on the Netflix show Making a Murderer. In 2003, Avery had filed a $36 million civil lawsuit against Manitowoc County, its former sheriff, and its former district attorney for wrongful conviction and imprisonment. Avery maintains he was framed.
A federal magistrate judge in 2016 found that the confession had been coerced. He's eligible for parole in 2048. The panel of judges on the 7th US Circuit Court Appeals ruled against Dassey and expressed that he spoke "freely".
