David Del Rio Takes Legal Action Against CBS in High-Profile Sexual Assault Arbitration Case

Share and Follow

The second season of Matlock kicked off with promise until behind-the-scenes drama emerged involving allegations against David Del Rio regarding the sexual assault of his co-star Leah Lewis, resulting in his dismissal.

CBS reimagined the classic Matlock series by introducing a gender-swapped protagonist played by Kathy Bates. This new version presents a unique storyline featuring a fictional lawyer aiming to join a top-tier law firm, coincidentally sharing the last name with the iconic character from the 1980s. In a twist, the season premiere uncovers that Matty, portrayed by Bates, has been concealing her true identity.

Matty is, in fact, Madeline Kingston, a wealthy woman on a covert mission to uncover the truth behind her daughter’s death. Her investigation focuses on suspects such as Olympia (Skye P. Marshall), Julian (Jason Ritter), and Senior (Beau Bridges), who all might have had access to critical documents that could have prevented opioids from circulating, ultimately leading to her daughter’s overdose.

As Madeline’s plan to expose the corruption at Jacobson Moore unfolds, she unexpectedly becomes closer to her colleagues, including Olympia, Billy (Del Rio), and Sarah (Lewis), none of whom appear to suspect the firm’s wrongdoing.

Before the off-screen scandal, the show hinted at an intriguing paternity storyline for Billy in its second season. The popular CBS drama, which debuted in September 2024, centers around the affluent, retired lawyer Madeline Kingston (Kathy Bates) masquerading as the impoverished widow, Matty Matlock, as she seeks justice and truth.

Before season 2 returned in October, the cast teased upcoming story lines for each of their characters. Days before the premiere, news broke that Del Rio was fired following an investigation after Lewis accused him of sexual assault.

CBS took action after Lewis reported an incident by removing Del Rio from set and making plans to write Billy off the show. The stars of Matlock haven’t spoken out publicly on the scandal so far but many have subtly showed their support for Lewis, who released a statement.

“David Del Rio, who plays Billy, who plays kind of, like, my counterpart, I’ve learned so much about comedy from him,” Lewis exclusively told Us Weekly in September 2024. “He comes from a theater background, so it’s like we’re always dancing and twinkling around set.”

Lewis said Del Rio had “one of the largest personalities and skill sets that I’ve ever been able to work with. So, it’s been playtime.”

Matlock was on hiatus from filming when news broke but production resumed on the second half of season 2 after Thanksgiving in November 2025. Del Rio’s Billy was written off after getting a larger arc in the first part of the season with an ongoing paternity surprise.

One day before the fall finale, Us confirmed that CBS has reopened its investigation into the incident. The network’s supplemental investigation concluded with CBS standing by its original decision to dismiss Del Rio from the show.

Del Rio’s attorney told Us in a March 2026 statement that the actor “initiated arbitration” against CBS Studios “to address false and misleading allegations that caused substantial professional and reputational harm.”

“At the arbitration, Mr. Del Rio will present real-time text communications and evidence that directly contradicts prior public characterizations of the interaction at issue. This evidence was not fully considered before adverse employment action was taken,” the statement continued. “Mr. Del Rio looks forward to resolving this matter through the appropriate legal forum and has faith that a full evidentiary review will establish the truth and restore his professional reputation.”
