There are two scenarios I can think of here:
1) He was disfellowshipped for something that should be allowed based on basic human rights. I'm thinking of the concept of disfellowshiping someone on the mear grounds that he associates with dissfellowshipped ones.
2) He was disfellowshiped with the JWs failing to obey their own rules (I'd see this as an agreed upon contract). As some have pointed to on this site, you can be disfellowshipped for any reason upon which 3 elders agree and appel commitee rarely reverse the first judgement.
Perhaps this is what happened here.
While this will likely have no impact on how the members of the religion view him, this may bring about legal consequences for future members who will suffer the exact same scenario.
