Bernie Ecclestone is unlikely to learn the outcome of the High Court trial brought against him by Constantin Medien until some time early in the New Year, after the sitting judge decided to reserve judgement on the case.

Ecclestone was the most recognisable defendant of four accused by Constantin of conspiring to cut it out of a share of the proceeds when CVC bought up BayernLB's stake in F1, and the case looks set to act as a benchmark for possible future actions being mooted in both Germany and Switzerland.

Early in the seven-week trial, Ecclestone was accused of making a 'corrupt bargain' with banker Gerhard Gribkowsky to keep the value of the stake at a sufficiently low price to attract CVC, a company he knew was open to retaining him as the head of the sport. Ecclestone was accused of paying Gribkowsky a $44m bribe to secure the deal, but has always insisted that the payment - which he does not deny making - was the result of Gribkowsky blackmailing him with the threat of revealing his tax affairs. The German has since been jailed on charges of bribery and tax evasion and is serving an eight-year stretch.

Despite interrupting the prosecution's closing argument - in which Phillip Marshall QC claimed that Ecclestone was driven by his desire wish to secure his position as F1 supremo - and suggesting that he found 'the idea of a bribe being paid to get rid of the banks more plausible than the idea of a bribe being paid to undertake an arrangement under which shares were sold at an undervalue', Mr Justice Newey has opted to reserve judgement on the case. He is now expected to take several weeks to consider the evidence, and decide whether BayernLB's shares were undervalued as a result of Ecclestone's involvement with Gribkowsky.

While the prosecutors pointed to 'evidence' submitted by Ecclestone's team that suggested CVC had initially offered a total of $1bn for a cut of the F1 pie, including - but not exclusively - Bayern's stake, the defence pointed out that the bank had been more than happy to accept a deal that valued its shares at $765m.

The outcome of the hearing could still have repercussions for Ecclestone. The 83-year old has already been indicted on bribery charges by a German court, although that case has been deferred until the New Year on the request of Ecclestone's legal team, while both Swiss authorities and, most recently, BayernLB are known to be considering the possibility of separate actions. The German bank this week gained access to the High Court documents as it prepares its case.

Shadow Attorney General Emily Thornberry, meanwhile, has repeated her call for the Serious Fraud Office to look into Ecclestone's financial affairs during an interview with the BBC's Newsnight programme.
