Here's an excerpt of the court's opinion:
[39] In any event, the pleadings will not require any examination of the "truth" of the respondents’ beliefs about blood transfusions. The misrepresentations pleaded are that it was falsely represented (i) that blood transfusions are an experimental treatment, and (ii) that blood transfusion treatment is ineffective. There is no indication on the record that either of these topics are the subject of any religious belief of the respondents. The record indicates that the respondents are opposed to transfusions as a matter of faith, not because they are experimental or ineffective.
By giving medical advice, the WT went beyond religion. Secular = sue = Lawrence wins
