Several things I discovered on Noveria today.
I decided I wanted to talk to Anoleis after dealing with Benezia and the Rachni Queen. So after exploiting the Lorik Quin glitch to pump up my renegade score, I used the glitch one final time to get the garage pass directly from him rather than from Gianna. I wanted to see if I could get Anoleis arrested after going to Peak 15 rather than before.
1) So the first thing I found out is that even if you convince Quin to testify, if your final run through the glitch gives him the evidence then you cannot have Anoleis arrested after coming back from Peak 15.
2) When you come back from Peak 15 and talk to Quin he will tell you that he presented his evidence about Anoleis's corruption to the executive board and they fired Anoleis and made Quin the new administrator.
3) Despite Anoleis supposedly being fired, he is still in his office and Gianna is still working to bring him down, only now she is pissed at Shepard because she has to continue wearing a skirt. Apparently, the executive board is taking its time to draft its termination notice to Anoleis.
4) If you talk to Lilihierax after coming back from Peak 15 he does not have any investigate options, but you can ask him to help with vehicle repair. Why Shepard would need a vehicle repaired, however, is unclear since you cannot get back into the garage.
