Munich law firm Westpfahl Spilker Wastl (WSW) was asked to investigate allegations of sexual abuse in the Archdiocese of Munich and Freising between 1945 and 2019.

The report, commissioned by the archdiocese, said there were at least 497 victims of abuse, mainly young males. Many other cases had probably not been reported, said the lawyers.

A spokesman for the former pope did not immediately respond to a request for comment. Benedict, now aged 94, has been living in the Vatican since resigning as pontiff in 2013.

The lawyers were tasked with finding out who knew what and any action they took. Attention has focused on Joseph Ratzinger, later Pope Benedict XVI, who was Archbishop of Munich and Freising between 1977 and 1982.

Presenting the report for WSW, lawyer Martin Pusch said Ratzinger had done nothing against the abuse in four cases.

“In a total of four cases, we reached a consensus that there was a failure to act,” said Pusch, adding the former pope had “strictly” denied responsibility in response to the accusations.
