Jul.5 (GMM) Convicted former F1 banker Gerhard Gribkowsky has lodged an appeal against the Munich court's ruling, according to media reports.

The 54-year-old German was sentenced to eight and a half years in jail for receiving millions in bribes from Bernie Ecclestone, raising the prospect that F1's high-profile chief executive could also be pursued.

But Gribkowsky's lawyer told Bloomberg news agency on Wednesday that they are appealing, and may also seek his release from custody on bail.

The lawyer, Daniel Amelung, said a new verdict is unlikely until 2013.

German news agency DAPD agreed that the appeals process in Germany takes several months.
