From the SC rejection thing again, snipped
The fact that the aforementioned “memorandum for the media”, published by the Attorney General office on the same day as the filing order, informed that the investigation could be reopened “if new evidence arose that could lead to serious, pertinent and consequential proceedings”, precisely points out that the order was issued pursuant to article 277-2 of the CPP.
In fact, if the investigation had been closed according to the terms of the first paragraph of the same article, it could not be reopened (cf. CPP, reviewed, 2016, 2nd ed., by Henriques Gaspar, Santos Cabral, Maia Costa, Oliveira Mendes, Pereira Madeira and Henriques da Graça, pp.929, 932-3.
Nope, it's still not making sense to me... and I'm trying lol
I don't have access to the book they cite, and they haven't made it clear why it couldn't have been reopened at all if it had remained archived under 277/1.
The "Memo" thing doesn't make any mention of the archiving article, so I'm still none the wiser.
