As I see this now, having read the full Judgement in English Translation, this Ruling does not make it any easier for a JW to leave the Org unscathed and with Honour.
It may make it slightly more difficult for the charge of Apostasy to be laid at your door, if you have been careful not to make statements that are definitely Apostate in nature. But, even though the Ruling clearly establishes you have the Human Right to Freedom of Thought and Conscience, the Judicial Committee are still free to institute your Disassociation by simply announcing you are " No longer one of Jehovah's Witnesses."
Then the effect on the individual, as we know is the same as being DF'd, but the actual Ostracism following from that would be difficult to challenge in Court, as the usual Defence of the JW Org that they cannot control what JW family decide to do, it is their free choice, may possibly still stand up.
Am I correct ? It would be possible to claim in Court that you still considered yourself a Jehovah's Witness, but would be a difficult thing to get a favourable Judgement on if you had in reality disassociated.
The most helpful thing for any wanting to simply fade away, that comes from this Judgement, is that the Truth of all the things that the JW Org claims were defamatory, 13 in all (?), has been established, in Court, your JW friends and family cannot claim they are not true, even less can they claim that they are " Apostate lies". So, the Judgement is helpful.
