But as the trial resumed on Tuesday, the 83-year-old Briton's lawyers asked the judge for an adjournment, as Ecclestone is suffering from a bad cold.
German publications like Bild and Handelsblatt - adding that Ecclestone's voice was also hoarse - published photos of the unwell-looking F1 supremo repeatedly coughing in court.
After two hours, the judge agreed to the adjournment until Wednesday, and told Ecclestone he appeared tired.
"I'm ok," Ecclestone replied.
But a court spokesperson told SID news agency that Ecclestone was examined by doctors and a medical certificate was issued.
In fact, Tuesday was arguably a good day for Ecclestone, with a public prosecutor appearing as a witness and admitting Gribkowsky had told a range of "fluctuating stories" to explain his sudden fortune years ago.
DPA news agency said Ecclestone's lawyers were "visibly pleased" when that testimony was given.
