I beg to differ with the prevailing sentiment that it cannot be done. Many are looking at this issue as one of trying to legally force JWs to associate with ex-members. It doesn't have to be that way for it to work.
Right now in many countries there are laws against inciting violent hatred toward groups of people. Such laws do not force everyone in the country to perform acts of kindness toward groups of persons. They only seek to prevent the public dissemination of hateful propaganda against groups.
In a similar way, Watchtower can be called to account for unduly inciting JWs to shun their ex-JW relatives. The crux of the issue is Watchtower inciting the members against their ex-JW family - not forcing JWs to associate with their ex-JW relatives.
JWs should have the right to freely choose whether or not they want to associate with their ex-JW relatives WITHOUT Watchtower inciting them not to and punishing them if they do. Most JWs shun their ex-JW relatives BECAUSE Watchtower tells them to and BECAUSE they face negative consequences if they refuse to comply.
If Watchtower is called to account for its incitement and is legally restricted from such incitements and is barred from punishing members who choose to associate with their ex-JW relatives, then over time conditions will change such that far less JWs will be shunning their ex-JW relatives. But they will still have the freedom - true, unfettered freedom - to do so if they wish. Right now Watchtower is practically coercing JWs to shun their ex-JW relatives so they're not really doing it of their own free will free of all duress.
So I think there is a case to be made but it has to be articulated the right way. It's not about forcing JWs to associate with ex-JW family. It's about punishing and halting Watchtower's use of undue influence to coerce JWs into shunning their ex-JW family. Yes no one can force JWs to associate with who they don't want to. So why does Watchtower get the right to force JWs to shun? It has to work both ways - no forcing either way.
