## Judicial career

Blacklock is considered one of the most conservative members of the Texas Supreme Court.
In May 2020, Blacklock wrote a concurring opinion calling into question the constitutionality of the government’s response to COVID-19, writing, "If we tolerate unconstitutional government orders during an emergency, whether out of expediency or fear, we abandon the Constitution at the moment we need it most." Blacklock was the first Justice to publicly dissent from the Texas Supreme Court's emergency orders closing courthouses throughout Texas because of COVID-19. In February 2021, Blacklock delivered a speech at the University of Chicago law school, entitled "The Constitution After Covid," in which he again expressed skepticism regarding the constitutionality of various COVID-era government measures.
In August 2021, Blacklock, writing for the Texas Supreme Court, ruled that the Texas Constitution "authorizes each legislative chamber to compel the attendance of absent members, by physical compulsion if necessary." The ruling was in response to Texas House Democrats fleeing the state to deny the chamber the quorum needed to vote on a controversial election bill.
In February 2022, Governor Abbott ordered the Texas Department of Family and Protective Services (DFPS) to investigate child abuse claims filed against parents who might be providing their transgender children with gender-transition procedures. After the ensuing legal battle, Blacklock wrote for a unanimous Court to strike down a state-wide injunction issued by a lower court judge blocking investigation into parents of transgender youths, but he also ruled that the governor did not have the authority to order such investigations. However, Blacklock and two other justices dissented from the Court's decision to block investigation into Doe's family, who had initiated the lawsuit against Abbott.
In February 2023, Blacklock wrote the Court's opinion holding that local government officials in Texas lacked the authority to implement COVID-related emergency orders that were more restrictive than Governor Abbott's more lenient COVID policies.
In June 2024, Blacklock wrote an opinion concurring in the Court’s decision to uphold Texas's ban on transgender medical treatments for minors. Blacklock's opinion criticized Bostock v Clayton County, the case in which the U.S. Supreme Court extended employment discrimination protections to transgender people. According to Blacklock, the Texas litigation "asks whether the sovereign People of Texas have the power, through their representatives in the Legislature, to answer moral and political questions about childhood transgender therapy in accordance with the Traditional Vision of what it means to be human, male and female. The answer is yes." He continued, "Only by commandeering the Constitution in service of the Transgender Vision, a moral vision that has never once—from 1836 to 2024—obtained the consent of the People of Texas, could any court give the plaintiffs what they seek." Blacklock's contrast between the "Traditional Vision" of human nature and the "Transgender Vision" has been widely commented upon and has been employed by advocates defending bans on transgender treatments for minors.

## Personal life

Blacklock lives in Austin with his wife and their three daughters, where they are members of Tarrytown Christian Church.
