There were, though, said to be discrepancies in the case, for example Walus did not fit the description of a tall, educated man, while some of the witness testimony was deemed to be inconsistent. Walus presented documentary evidence to dispute Wiesenthal's claim, which the court found to be compelling. As a consequence, the U.S. Justice Department reversed its decision, dropped its suit and paid Walus $34,000 in legal costs.
The Walus case is seen as important for two main reasons. Firstly it has been used as evidence to discredit the work of Simon Wiesenthal and the use of uncorroborated witness testimony in such cases. Indeed, it has sometimes been a cause célèbre for Holocaust deniers, with exaggerated claims that Walus was accused by Wiesenthal of being a Gestapo officer or even of being the Beast of Kielce.
Alternatively, others claim that rather than discredit Wiesenthal, the case illustrates that the US Department of Justice has not been willing to hunt out suspected Nazis and that the case was closed too early for political reasons. For example, Israel's chief investigator of Nazi war crimes, Menachem Russek, criticized the Department of Justice for its decision not to retry the case.
Whatever the merits of the case or the controversy, the trial had a negative impact on Frank Walus, who claimed to have been physically attacked on numerous occasions.
Walus died in 1996 after several massive heart attacks.
