The Daily Mail are a bit behind in reporting this.
The decision dates back to July and the rejection of the appeal to the beginning of this month.
The PB are preparing to appeal to the ECHR so I suspect it could be a long time before JW's are affected. In fact the system for collecting tax refunds is being simplified so it can be claimed on ALL donations to the congregation up to a set figure. (I think this will be £5000 pa so most congregation donations will be covered.)
