Crediting French extradition custody 1:1 against total imprisonment sentence in criminal revision

The Federal Court of Justice (5th Criminal Senate) dismissed the defendant's revision as unfounded but modified the judgment to order that time spent in French extradition custody be credited 1:1 against the total imprisonment sentence imposed by the Landgericht Berlin; the defendant bears the costs of the appeal and necessary expenses of the auxiliary litigants. The case concerned a criminal appeal challenging a conviction, where the primary operational issue was the calculation of pre-trial detention credit under international judicial cooperation principles. The court applied the doctrine of full temporal equivalence for foreign detention periods, ensuring that time served under an extradition warrant is treated identically to domestic pre-trial detention for sentencing purposes.
