For those who like summertime puzzles, the Court has now published a factsheet on its website on "Extra-territorial jurisdiction of ECHR States". It contains the most important decisions and judgments on extraterritoriality of the ECHR of both the former Commission of Human Rights and the Court. The recent Al-Skeini and Al-Jedda judgments have been included. When reading through these very short summaries, one realises once more that the conundrum of possibilities has not found definitive answers yet. And even for those who do solve the puzzle of possible contradictions, the factsheet indicates that "This factsheet is not exhaustive and does not bind the Court".
The full list of factsheets, several of which have been added or updated in the past few months, can be found here.
