The Foreign Office (FCO) said the British Government is "disappointed" with the ruling and has taken the decision to appeal it.
The judgement has potentially significant and far reaching legal implications. The normal time limit for bringing a civil action is three to six years.
In this case, that period has been extended to over 50 years despite the fact that the key decision makers are dead and unable to give their account of what happened.
Since this is an important legal issue, we have taken the decision to appeal. In light of the legal proceedings it would not be appropriate for the Government to comment any further on the detail of the case.
