The stickers were found in their stadium, Rome's Olympic Stadium, which they share with AS Roma, during a match against Cagliari in October
Following the incident, Italian soccer authorities ordered stadiums to hold a minute of silence at their next matches while a passage from Anne Frank's diary is read out.
Investigations showed that 13 Lazio supporters were found guilty of applying the stickers. The 13 have been banned from going to sports events.
Anne Frank was born in Germany but her family fled to the Netherlands to escape the Nazi takeover. They lived in hidden rooms in Amsterdam before they were discovered by German occupiers and deported to concentration camps.
She died in the Bergen-Belsen camp aged 15 and her diary recounting the family’s time in hiding became a centrepiece of Holocaust literature.
The tribunal said Lazio did everything in its power to prevent discriminatory material being introduced in the stadium, noting the stickers were too small to be detected.
However, Lazio was still held "objectively" responsible for the incident as the supporters' representative, the Italian FA said on Thursday (www.figc.it).
The tribunal opted not to ask Lazio to play two matches behind closed doors as the Italian FA prosecutor requested, as this would also punish fans who did not play a part in what happened.
