In the fraud process surrounding the Volkswagen emissions scandal, several defense attorneys have criticized the lack of disclosure of information by the public prosecutor's office.
Some are informed late, some questions are first answered in the negative and shortly thereafter in the affirmative, said a lawyer on Tuesday in the trial at the Braunschweig regional court.
"We can't conduct a procedure like this," he said.
"That is an impossibility," added a colleague.
For almost a year, the proceedings against four former executives of the car manufacturer have been progressing rather slowly.
The accused are accused, among other things, of commercial and gang fraud with deceptive programs in the exhaust gas control of millions of diesel cars.
The manipulations known as "Dieselgate" were exposed in autumn 2015.
All of the defendants in the trial have denied primary responsibility for the scandal.
In response to criticism of the way the prosecutor's office worked, presiding judge Christian Schütz renewed his call for essential information to be shared with all those involved in the trial.
Similar allegations had been made earlier in the course of the proceedings.
It was initially unclear on Tuesday whether the public prosecutor's office would react with a statement.
In terms of content, the trial was continued with the testimony of a public prosecutor who reported on a witness hearing in 2016.
As an interrogator, the 58-year-old spoke to a VW lawyer responsible for product safety that year.
She admitted that eight years after this interrogation, the memories are not fresh.
On the basis of protocols, however, she reproduced some of the content of the conversation about which the 2016 interviewee also spoke with the former VW boss Martin Winterkorn.
