I know of one that was cancelled by means of declaring the baptism of the young lady in the first place to be null and void, due to her mental condition at the time of baptism. She only did this so as to be able to have full contact with her JW grand-parents, she knew TTATT by this time.
It was funny when she was invited to the K.H for the Elders to explain their decision to her, she turned up in jeans, with a tattoo or two, and her hair dyed pink and purple, bless her !
Another slightly off topic one, but involved an apology, was abrother I worked with had been taken off all privileges due to the conduct of one of his adult (over eighteen) sons who was not living at home at the time of his "offense". The Bro who had been demoted took it to about three different C.O's as time went on, the third C.O looked in to it, saw that it was unjust and made the Body of Elders issue an apology from the platform !!!!
The Bro never took up privileges (Elder) again, and last I heard had not even answered in a meeting since he got his apology, why he keeps going is beyond me.
