European Court of Human Rights
I was just scrolling though the "Convention for the Protection of Human Rights and wondering if this could help.
Underneath all the complexities of this case is a basic incredulous question that we ourselves and people we may tell of this situation express: "Surely they cannot do this?!" In this respect it's a matter of morals and livelihood. On the Convention of Human Rights, Article 8: Right to respect for Private and family Life ('protection of health and morals') relates to Article 17 Prohibition of Abuse of Rights ('destruction of any of the rights and freedoms').
Reading through our various stories, a lot of us are going to find it very difficult or impossible to recover from this mess by means other than 100% return of savings. Besides losing our savings, we're losing the security and protection that they offer - I refer to them as my 'life-line' - but this merely brings words to the effect 'very sorry for what you must be going through, etc'., as though the 'felt' consequences can only be met by sympathy. Possibly, and this would be a question which would need to be debated by more clever minds on this forum, we could, or could also, approach the European Court of Human Rights on the basis of the effect of the bank's closure on 'health and morals'. The physical and material impingement we are suffering and can expect to continue to suffer would be allied with the threat to emotional and psychological health, and we know of course, who the action would be brought against!
(Just another thought!)
