"There is just no gathering mob of inmates seeking DNA testing in the federal courts," he said. "Prosecutors are rightly giving it to them in states courts."
Lawyers for Skinner today praised the decision.
"We look forward to making our case in federal court that Texas' inexplicable refusal to grant Mr. Skinner access to evidence for DNA testing is fundamentally unfair and cannot stand," said Robert C. Owen, clinical professor of law at the University of Texas at Austin.
Skinner told ABC's Ryan Owens last spring, "I never got to grieve for my girlfriend's loss. I woke up, my family was dead, and I am holding the bag for something I didn't do.
"I have lost 15 years of my life sitting here for something that I didn't do, and now they still want to kill me even though I have exculpatory evidence that proves my innocence. It is all something out of the 'Twilight Zone.'"
