Quite a detailed piece on this website and that time-barred aspect is "misjudged"...

MCFC’s reliance upon the five-year limitation period and the ‘
release’ from the May 2014 Settlement Agreement appears misjudged. The May 2014 Settlement Agreement expressly states that the same ‘
will be subject to on-going and in depth monitoring, in accordance with the applicable rules’ and that if MCFC ‘
fails to comply with any of the terms of [
the May 2014 Settlement Agreement]
, the… CFCB Chief Investigator shall refer the case to the [
AC]
, as foreseen in Art. 15 (4) [
of the PRCFCB]’. The mere opening of proceedings is sufficient to stop time from running.[11] The Investigation commenced in March 2019, fewer than five years after the May 2014 Settlement Agreement. Further,
if the CLFFPR violation allegations against MCFC are proven – as the AC Decision indicates they are – then MCFC was never entitled to a ‘
release’ from the May 2014 Settlement Agreement and the CFCB was entitled to commence the Investigation/make the Referral Decision against MCFC.[12] This encapsulates a basic legal principle that no one shall benefit from their own wrongdoing.
