Sheboygan County Judge Angela Sutkiewicz ruled Avery had not met the legal standard to receive a new trial, according to a copy of the decision posted online by the Milwaukee Journal-Sentinel.
An attorney for Steven Avery said she intends to file an amended appeal after a judge denied his request for a new trial.
Meanwhile, Brendan Dassey, who was convicted alongside his uncle Avery, recently had his murder conviction overturned, with a federal judge ruling that his confession was obtained by investigators after he had been given "false promises".
Avery's attorney, Kathleen Zellner, told WBAY-TV in Green Bay, Wis., that she plans to file a new petition because she has new test results and witness affidavits. The case gained national attention in 2015 after Netflix aired "Making a Murderer", a multi-part documentary examining Halbach's death.
Avery, 54, now serving a life sentence (without the possibility of parole) for the 2005 death of photographer Teresa Halbach, has been working every possible angle with Zellner to have his case heard again. "The scientific testing is not completed, we remain optimistic that Mr Avery's conviction will be vacated".

The actor had been in jail for nearly three months now, after which he is finally getting to come out! The unfortunate incident took place on February 17 when the actress on her way from Trishur to Kochin.
Avery served 18 years in prison for a crime he did not commit.
It was in light of Dassey's conviction having been overturned that Avery's defense team was attempting to present new evidence to the court in an effort to get a retrial.
She also maintains that a spare key for Halbach's sport utility vehicle found in Avery's bedroom was planted by sheriff's deputies. The documentary series calls into question the investigation and trial that put Avery and his nephew, Brendan Dassey, behind bars, and alleges the investigators and police in the case planted evidence and otherwise manipulated the outcome of the trial.
'Because the State did not need to establish motive, it did not spend any time trying to figure out why Ms. Halbach was murdered, ' Zellner wrote.
In November, Zellner announced that an agreement had been signed to begin independent scientific testing on several critical pieces of evidence. Dassey remains in custody.
