Sorry I am confused here. Let's bullit-point your O.P.
A) 35 years ago a brother was caught peeking at a sister whilst she took a shower.
B) she told the elders he was rependent and lost privaliges.
C) Now 35 years later she intends suing the watchtower.
With the greatest respect she needs a bloody good laywer.
On a more serious note has anybody heard of Cliff Richard? ( His band members were called " The Shadows" and converted to Jehovers witnesses) Anyway I think Cliff Richard is a resent and better example of why we need a statute of limitations on such charges, but the sister you knew is a good example.
