On Thursday, September 28, 2023, the Presiding Disciplinary Judge of the Supreme Court of Colorado approved a stipulation for discipline and suspended attorney Thomas Blumenthal for one year and one day. Blumenthal’s suspension was due to his violation of the Colorado Rules of Professional Conduct while representing clients in two criminal cases.

The case is entitled “People v. Thomas Blumenthal,” with case no. 22PDJ062.

In the first case, Blumenthal failed to inform the court or the deputy district attorney (DDA) that he would be unable to appear for the trial due to his suspension, which was scheduled to take effect on December 1, 2021. Blumenthal did not notify the court or the DDA until 4:32 p.m. on the eve of the trial when he moved to withdraw from the case. As a result, the court had to continue the case, and Blumenthal’s client was left without representation.

In the second case, Blumenthal engaged in aggressive and intimidating behavior towards the DDA, including leaning over the prosecution’s table, accusing the DDA of lying, and using physical intimidation. Blumenthal’s behavior was seen as completely out of control and scary, and the presiding judge feared that he might physically harm the DDA. The cases were eventually transferred to another division under a different DDA.

Blumenthal’s conduct violated several rules of professional conduct for attorneys, including using means that have no substantial purpose other than to embarrass, delay, or burden a third person, engaging in conduct prejudicial to the administration of justice, exhibiting bias against a person based on their race, gender, religion, national origin, disability, age, sexual orientation, or socioeconomic status, and engaging in conduct that directly, intentionally, and wrongfully harms others and adversely reflects on the lawyer’s fitness to practice law.

The case file is public per C.R.C.P. 242.41(a). Blumenthal’s suspension is effective November 2, 2023, and he must prove by clear and convincing evidence that he has been rehabilitated, has complied with all disciplinary orders and rules, and is fit to practice law in order to be reinstated.

According to avvo.com, Mr. Blumenthal is a personal injury attorney in Denver, Colorado. He attended the University of Denver Sturm College of Law, graduating in 1985. He acquired his law license in Colorado in 1986.
