The Bundesliga game between VfL Bochum and Borussia Mönchengladbach, which was called off after the cup was thrown at assistant referee Christian Gittelmann, was scored 2-0 for the visitors.
The German Football Association announced this on Thursday after a single-judge procedure by the DFB sports court.
Bochum had demanded a replay after the scandal.
VfL lawyer Horst Kletke said on Wednesday the German Press Agency.
First, the "image" reported on the demand of the climber.
"We condemn the cup throwing, it's a massive crime, there's nothing to sugarcoat it, it's condemnable, it's unbearable," said Kletke.
"But if a criminal throws a cup, VfL Bochum is not to blame."
The offender bought his drink completely legally and the club was not at fault for the crime.
"That's why the game has to be repeated.
That's in paragraph 18, the fourth point of the DFB's legal and procedural rules," said Kletke.
There it says: "If a national game is stopped prematurely through no fault of either team, it must be repeated at the same place." According to Kletke, Bochum was only at fault if the perpetrator had smuggled the cup into the football stadium and the VfL security guards overlooked him had.
According to a joint statement from the police and the public prosecutor's office on Tuesday, there is a suspect.
It is a 38-year-old from Bochum.
The game against Gladbach was stopped on Friday evening when the score was 2-0 for the guests in the second half after assistant referee Christian Gittelmann was hit by a drinking cup.
