the Danny Masterson rape trials were monitored and influenced by Sea Org members

Specifically, the prosecution was closely monitored and the defense was influenced by high-level OSA (Office of Special Affairs) operatives, working under the direct control of Scientology leader David Miscavige. He also ordered payments for Masterson's defense efforts.
All the non-lawyer stuff was done by Sea Org members.
Next week there will be a court hearing about how Scientology attorneys gained access to evidence and documents used in the trials.
The defense lawyers in the rape trials will have to answer some questions, but they likely had nothing to do with the data leaks. That would have been the work of "hired" Sea Org members doing background research and following up all kinds of rumors and manufactured allegations. Much of this research was actually legitimate, as it involved Church members who witnessed or were involved in the rapes or the cover-ups.
