Gerhard Schröder's lawyer sharply criticized the behavior of the Bundestag's budget committee in the dispute over the abolition of former chancellor privileges.
"At best, the way the budget committee deals with this process is undignified," said lawyer Michael Nagel on Friday in a statement available to the German Press Agency.
He was aiming at the statement by committee chairman Helge Braun (CDU), who on Thursday rejected a conversation with the ex-chancellor about the cancellation of his office privileges and described the discussion about it as "undignified".
When Braun titled a legal review of the committee's decisions that way, he revealed "an idiosyncratic understanding of the rule of law," said Nagel.
According to the decision in mid-May, Schröder's former chancellor's office is to be "put on hold" and all related positions are to be wound up.
The former chancellor had previously been heavily criticized for his ties to Russia and Russian President Vladimir Putin.
Adopted with a large majority
Braun had emphasized that the decisions of the budget committee had been taken with a large majority and were now to be implemented by the federal government.
Schröder's lawyer accuses Braun and the other members of the budget committee of not having explained the measures against the SPD politician in more detail.
Schröder's connections to Russian corporations or Putin were not mentioned in the application that was approved.
The background was the fear that this would be legally vulnerable.
Last year, more than 400,000 euros flowed from the state coffers for personnel expenses in Schröder's office.
According to the committee decision, the former chancellor is still entitled to a pension and personal protection.
