The only way the next case after this could go (following the real rules) is that Mia Fey doesn't die but insteads prepares a lawsuit against Redd White for blackmail and illegal surveillance which starts by Mia Fey finding her phone tapped and office ransacked while she was out. It then starts with her calling the police and Detective Gumshoe being the first on the scene. Because she's a lot more cautious and smart in this version; she hid the evidence somewhere that Redd White wouldn't think to look and the papers and stuff survive.
Otherwise Phoenix gets disbarred in that case for all the stunts he pulls. He isn't supposed to be disbarred in canon until post game 3.
