PI ("provider independent") address space - this could theoretically be used. You do not have to ask the old ISP or RIPE for permission. You just register the routes in the RIPE database, ask the old ISP to stop announcing them, and start announcing them via BGP. PI space has other disadvantages, though, like "much harder to debug if some goal in the Internet cannot be reached", so we usually recommend to the customer to return his PI space to RIPE and accept PI space from us
This should read "and accept PA space from us". Sorry for the typo. (I've exchanged a few more mails with Andreas in between, and it seems that the issue isn't explained clearly enough in the RIPE LIR course - but in any case it's documented in the "policies and procedures" RIPE document. The network in question is PA space, and the answer is "you can route it for a certain time, if both ISPs agree, but then the PA space HAS to be returned to the ISP it belongs to").
