The three defendants have indicated that they will not be present at the hearing in Bellinzona for a variety of reasons, including fear of travelling because of coronavirus contagion.
Swiss Linsi, 70, former German Football Association (DFB) presidents Wolfgang Niersbach, 69, and Theo Zwanziger, 74, and 78-year-old former DFB General Secretary Horst R. Schmidt are being prosecuted for "fraud".
They are accused by the Swiss Federal Prosecutor's Office (BA) of concealing from the DFB the true destination of a transfer of 6.7 million euros ($7.6 million today), paid in 2005 by the organising committee to former Adidas boss, the late Robert Louis-Dreyfus, via FIFA.
The case of former World Cup organising committee chairman Franz Beckenbauer is being heard separately because of the former Germany captain's poor health.
The investigation was prompted by a report in German publication Der Spiegel in 2015 that Germany had used a secret fund of 10 million Swiss francs (6.7 million euros at the time) to buy votes and obtain the rights to host the competition at the expense of South Africa.
Beckenbauer is suspected of having asked Louis-Dreyfus, to contribute to this fund shortly before the vote on the host in the summer of 2000.
Louis-Dreyfus was allegedly reimbursed by the German Football Association on the pretext of expenses related to a FIFA gala evening, which ever took place.
Zwanziger, Niersbach and Schmidt have also been charged with tax fraud in Germany and the case is expected to come to trial in the coming months.
