<P> The entire main cast from the previous season returned . In August 2017, it was announced that Philip Winchester would reprise his role as Assistant State's Attorney Peter Stone from Chicago Justice, appearing around the midpoint of the season . New show runner / executive producer Michael Chernuchin told Entertainment Weekly that Stone's character would be coming in as an antagonist and that he will be a foil for A.D.A. Barba (Raul Esparza) this season; Stone's character isn't necessarily taking his (Barba's) job . "There's more than one A.D.A. in New York (...) Philip will come in and he won't be the nicest person our characters have ever met . What he's going to be doing, too, is basically bringing all of the franchises into one . He's connecting Law & Order, the Chicago franchises and now SVU ." </P> <Ul> <Li> Mariska Hargitay as Lieutenant Olivia Benson </Li> <Li> Kelli Giddish as Detective Amanda Rollins </Li> <Li> Ice - T as Detective Odafin "Fin" Tutuola </Li> <Li> Peter Scanavino as Detective Dominick "Sonny" Carisi, Jr . </Li> <Li> Raúl Esparza as A.D.A.
