On January 12, 2024, Nicholas Baxter tells Detectives Riley and Shaw that he has just been appointed District Attorney. However, in Last Dance (2024), his predecessor Jack McCoy resigned from the position on February 22, 2024.
Baxter and Price say McCoy worked at the D.A.'s office for 30 years, meaning he started in 1994. While the character was introduced that year, he was already a seasoned prosecutor who had been with the office since the '70s.
