"We will contest every charge and prove that there was no mental manipulation."Oh, really?
That is going to be a very, very hard thing to prove. After all, Scientology is all about mental manipulation!
How do you suppose the lawyer is going to prove that an organization that boasts that its "technology" can handle any and all "mental problems" does not practice mental manipulation?
Let's see. L. Ron Hubbard's book Science of Survival, a rather large book, is specifically and only about how to use Hubbard's "Tone Scale" to evaluate and control people using mental manipulation.
Hubbard's extensive issues about surveys and marketing are all about how to control people without their consent or knowledge. His advices to "registrars" (salesmen) are all about how to use tricks and how to persist until they "get the sale".
Hubbard carefully selected the images for his book covers because, he believed, they would mentally manipulate people so they would buy his books without knowing why they felt compelled to do so. The most famous image is, of course, the "Dianetics volcano" on Dianetics, the Modern Science of Mental Health, which was supposed to trigger OT III and force people to buy the book.
Hubbard's famous "TR" drills are all about controlling people. These drills are billed as "communication drills" but that isn't what they teach. Their purpose is to teach a person how to control others. The TR0 drills train the person to not react in any way to what others might say. The rest of the TR drills train the person to get an answer or, especially, to get compliance from others by means of mental manipulation. These drills have nothing to do with how to have normal, social conversations, they are all about control and how to force compliance.
In fact, when you get right down to it, there isn't any part of Scientology that isn't about mental manipulation. Scientologists are all busy being controlled and working to control others through their "superior mental technology".
So, just how is it that this lawyer thinks he can prove that mental manipulation wasn't involved?
Ah! Perhaps he will contend that, because Scientology's attempts at mental manipulation are so feeble and ineffective, it really shouldn't count. In other words, their only defense will be to prove that Scientology doesn't work!
