Yesterday, as the court case continued, state prosecutors questioned a number of other associates and relations of the Duke and Diego in Palma.
The Duke has as yet to be formally charged but is reportedly accused of misdirecting part of some 6m euros sent to his not-for-profit Noos Institute by regional governments, including the PP's Balearic government when Jaume Matas was president, to organise sporting events.
The events in question happened between 2004 and 2006, when the duke stepped down as head of the institute.
State prosecutors have already applied for bail to be set at just under 8.2 million euros while the Balearic government is pushing for just under 3.5 million euros.
And now, nearly a year after the case opened in Palma, the Duke could find himself back in court here in Palma where the state prosecution want to question him about three alleged fiscal crimes committed between 2007 and 2008.
The Balearic High Court confirmed the prosecution's application yesterday which is apparently based on new evidence that tax was apparently evaded on some 240'000 euros in 2007 and then on two other occasions on figures of over 120'000 euros in 2007 and 2008.
The Duke's former partner, Diego Torres, has used his constitutional right to remain silent since appearing in court last February.
