There is also an interesting argument that as the der spiegel leaks were on Dec 2016 and more in Nov 18. When the specific emails they seek to rely on came out is hugely important. If they came out in the Dec 2016 release the PL only had until Dec 2022 to file the charges and are therefore out of time.No. In essence it resets the time to file the claim. Otherwise, you could get away with things by dishonestly concealing them long enough. It is a high hurdle to prove dishonest concealment though
I think a strong argument can also be made that if there is no legitimate further relevant documentation than the accounts (ie we show once again that the leaked emails are doctored and irrelevant) then the trigger date is the filing of those accounts.
