The court in that case concluded that while entitlement to pre-judgment interest is a substantive
right (akin to the
right to sue, for example), the mechanism for determining the
amount of pre-judgment interest in a particular case is
procedural in nature.
One notable example is A v UK (2009) 49 EHRR 29, [2009] All ER (D) 203 (Feb), where the ECtHR held that the detention of terrorist suspects based «solely or to a decisive degree on closed material» always
amounts to a breach of
procedural fairness as guaranteed by the European Convention on Human
Rights)(ECHR)[220].
