happyex,
I am so sorry. My sympathies to your and your family at this difficult time, I am facing a similar situation with my dad in kidney failure and lung cancer (not in final stages though). My only personal experience in this area is my ex-father-in-law's funeral- he was not an active JW at the time of his death, but he was baptized. He had many "worldly" relatives and friends- and they wanted to say a few words to eulogize him. They insisted on it the day of the funeral. His funeral was graveside, and the elder did say after his discourse that a few of Jim's relatives wanted to say a few words, they came up & said things about "Big Jim"- I have never seen it before at a "JW" funeral.
Apparrently the aftermath was such: the elder who gave the funeral talk was very worried that he would "get into hot water" over losing control of the way the JW funeral was carried out....
Bottom line....the guy is still an elder today so obviously no judicial action was taken to him.
Perhaps an insistence on your DF'd families wishes to speak or play music at the crematoriam, more forseful insistance will help.
Welcome & hope to hear more from you
