On 20 December 2021, the PRA imposed a penalty on SCB, reduced from £66.5m for early settlement discount, in respect of failings in its regulatory reporting governance controls (relating to a USD liquidity metric), and for failing to be open and co-operative with the PRA in respect of one of the breaches. The latter failure arose from the speed with which the PRA was informed of the suspected breach and consequent investigation; it underlines that firms cannot afford to wait until they have all the answers before informing the regulator.
Javan Herberg QC advised SCB in relation to this matter.
On 17 December 2021, the FCA announced that it had fined HSBC Bank plc just under £64 million for failings in its anti-money laundering processes. The fine concerned weaknesses that were said to be present in HSBC’s legacy transaction monitoring systems over an eight year period from March 2010.
Javan Herberg, Simon Pritchard and Sean Butler advised HSBC in relation to this matter.
Represented the FCA in an appeal on an important point of statutory construction. The High Court ruled that the FCA’s enforcement action against Carillion plc (in liquidation) did not amount to an “action or proceeding” under s.130(2) and therefore was not subject to the statutory stay.
Javan acted for Lloyds Bank in this appeal concerning the bank’s review of the sale of interest rate hedging products. The Judgment will be of some significance for banks and financial services providers in relation to attempts to by-pass conventional mis-selling claims (or FOS complaints) and use the DISP Rules to render actionable claims that might otherwise be out of time or out of scope.
The Court handed-down judgment following a trial of two preliminary issues arising in a claim against Lloyds Bank regarding the bank’s review of the sale of interest rate hedging products. Javan acted for the successful defendant.
On 5 February 2019 the FCA published the Final Notice in the matter of PS, following a contested RDC hearing, imposing a penalty of £32,200 in respect of (non-deliberate) conduct found to be contrary to APER 2 and 3. The APER 3 finding sanctions, for the first time, communications between fund managers in the context of a share placing and an IPO which (the FCA found) were intended to get investors to use their collective power and thereby undermine the proper price formation process. The decision raises (and does not entirely answer) issues as to the proper limits of buyer communications in such markets, as well as the relationship with competition law principles. Javan Herberg QC acted for PS. The Final Notice can be viewed here.
Acted for ex-CEO of Barclays Bank on application (brought jointly with Bank) to stay the high profile trial of the claim of PCP (Amanda Staveley) for some £700m in respect of alleged fraudulent misrepresentations in connection with capital raising from Qatar during the credit crunch.
