letter against auxiliary bishop Jan Niënhaus in 2000, and in 2007 ordained a father known to have abused pupils in a Twello boys boarding school to acolyte (leading altar servers) in Oldenzaal. In 2010, he said on live television show Pauw & Witteman that Wir haben es nicht gewußt ("We did not know about it"). Martinus Jansen, bishop of Rotterdam (1956–1970), in 1965 reappointed a priest convicted of molestation elsewhere in his diocese. He also appointed a priest, that he knew had committed sexual abuse in a pastoral relation in 1965, to religious teacher in an Oudenbosch boys boarding school; the priest went on to sexually abuse three underage boys there around 1970. Philippe Bär, bishop of Rotterdam (1983–1993), transferred multiple priests accused or found guilty of abuse to other dioceses when he could no longer maintain their position in his own. Did not undertake action in at least five cases, and is known to have had sex with underage students of his own priestly seminary. Ad van Luyn, bishop of Rotterdam (1993–2011), when leading a Salesian congregation in 1979 urged the police to stop prosecuting a Rijswijk priest in a case of sexual abuse; the suspect was transferred to a parish in Terneuzen where he abused children again. In 1995 he appointed a priest, who had already confessed to abusing children in 20 separate cases, to doing pastoral and youth work; when the priest transgressed again, Van Luyn waited six months before transferring him to Amersfoort in the archdiocese of Utrecht, where he once again abused children. He ignored complaints by three victims in 2002, 2008 and 2010 and covered them up. Guillaume Lemmens, bishop of Roermond (1932–1957), maintained a priest in his diocese for 20 years, even though he knew the man was convicted in 1941 for abusing two boys and a girl in Sittard. He died in 1960; in 2011 the diocese acknowledged that a 1946 complaint against the priest for abusing a seven-year-old girl in Doenrade was valid, and that the priest in question (then director of a Heel lunatic asylum and a Sittard hospital) was examined by the police again in 1952. Petrus Moors, bishop of Roermond (1959–1970), appointed a Belgian priest, knowing he had been convicted of sexually abusing boys, to chaplain in Broekhem-Valkenburg in 1959, where the chaplain abused boys once more. Nevertheless, Moors appointed the chaplain in 1966 to Hulsberg and in
