On August 26, 2019, Governor Greg Abbott announced his intention to appoint Bland to the Supreme Court of Texas to replace Justice Jeff Brown, who had been confirmed by the United States Senate as a District Judge for the U.S. District Court for the Southern District of Texas. She assumed office on September 4, 2019, when Brown was commissioned as a federal district judge. She was sworn in on September 11, 2019.

Bland served as the judge of the 281st Judicial District Court in the civil trial division of Harris County, Texas, having initially been appointed by then–Governor George W. Bush in 1997. In 2003, she was appointed to the First Court of Appeals by then-Governor Rick Perry. Bland sat as an appellate justice for 15 years, winning elections in 2004, 2006, and 2012. Along with many other Republican incumbents on the intermediate appellate courts, she lost her re-election bid in 2018, and returned to private practice.

In November 2010, U.S. Supreme Court Chief Justice John Roberts presented Bland with the William H. Rehnquist Award, which is given annually by the National Center for State Courts to a state court judge who exemplifies the highest level of judicial excellence, integrity, fairness, and professional ethics.

The Texas Association of Civil Trial and Appellate Specialists (TACTAS) recognized Bland as Trial Judge of the Year in 2002 and Appellate Justice of the Year in 2006 and 2014.

From 1990 to 1991, she clerked for Judge Thomas Gibbs Gee of the United States Court of Appeals for the Fifth Circuit. She then went on to practice law with Baker Botts from 1991 to 1997, focusing on civil trial and appellate work.
