Assuming Ulbricht is found guilty and then appeals, will he get a second chance to challenge the FBI's account of how they found the server in the first place?

Assuming Ulbricht is found guilty and then appeals, will he get a second chance to challenge the FBI's account of how they found the server in the first place? Nicholas Weaver [1] seems to think they could have admitted to owning the servers (and thus having standing to contest the FBI's story about how they found it) without harming their case: > Such a declaration is not an admission of guilt: it can only be used by the prosecution if the defendant testifies. But I don't know if that door will be closed to them on appeal...
