In her opinions, she has questioned the legal reasoning which legalized
abortion, advocated streamlining
death penalty cases, invalidated a federal ban on possession of
machine guns and advocated toughening
bankruptcy laws. In 2006, Jones found that a death row inmate who had filed a
pro se motion to drop his appeal while his attorney was abroad could not later reinstate his appeal. In June 2017, Jones dissented when the court found that a university did not violate the
Due Process Clause or
Title IX when it expelled a student for committing a
campus sexual assault and his girlfriend, who had recorded the assault and shared the video on social media. In May 2018, Jones wrote for the court when it found that
Texas Senate Bill 4, which prohibits local governments or public employees from "endorsing"
sanctuary city policies, did not violate the
First Amendment.
McCorvey v. Hill Jones attracted attention for her opinion in the case of
McCorvey v. Hill (2004), which was a request by
Norma McCorvey – the 'Jane Roe' of
Roe v. Wade – to vacate the finding of that case. Jones joined the Fifth Circuit in rejecting the petition on procedural grounds, but she took the unusual step of handing down a six-page concurrence to the judgment of the court. The concurrence credited the evidence presented by McCorvey and sharply criticized the Supreme Court's rulings in
Roe and in a less famous case that was decided simultaneously,
Doe v. Bolton. She quoted Justice
Byron White's dissent in the latter that described the Supreme Court's decision as an "exercise of raw judicial power". She concluded: "That the court's constitutional decision making leaves our nation in a position of willful blindness to evolving knowledge should trouble any dispassionate observer not only about the abortion decisions, but about a number of other areas in which the court unhesitatingly steps into the realm of social policy under the guise of constitutional adjudication."
Adams v. All Coast Jones dissented when the 5th Circuit denied
en banc in a case regarding what constitutes a 'seaman'. The majority ruled that liftboat workers are not exempt from overtime pay, and Jones accused the majority of flouting
Encino Motorcars v. Navarro. ==Controversy==
