take place. The company also said there was group housing and pair housing for some monkeys, but the BUAV chose not to show that. Covance said they planned to upgrade the housing to comply with future European Union guidelines. Jane Goodall, a primatologist, described the monkeys' living conditions as horrendous. Another primatologist, Stephen Brend, argued that using monkeys in such a stressed state was "bad science", and that trying to extrapolate useful data in such circumstances was an "untenable proposition." The environment minister for North Rhine-Westphalia asked the public prosecutor to investigate, and said that if the allegations were borne out, the company would lose its licence to keep primates. According to the European Biomedical Research Association, a lobby group, the authorities inspected Covance and insisted that the company install video cameras to monitor staff working with primates. Covance appealed through the courts, which ruled that video monitoring would infringe the rights of the staff. The public prosecutor's office viewed the film and questioned witnesses, and concluded that Covance "had not rendered themselves liable to prosecution" and that the state veterinary officer "had not failed in his supervisory duties." Vienna, Virginia, United States People for the Ethical Treatment of Animals (PETA) alleged similar conditions in Covance's Vienna, Virginia, lab when it sent an undercover investigator to obtain a job there as a technician from April 2004 to March 2005. Subsequent inspections by the United States Department of Agriculture (USDA) resulted in 16 citations in April 2006. The USDA declined to give details; according to Covance the violations ranged from "administrative issues to scope of veterinary authority." The company agreed to pay a settlement of $8,720. In June 2005, Covance filed a lawsuit in the United States against PETA and the investigator for fraud, breach of employee contract, and "conspiracy to harm the company's business by deceitfully infiltrating and videotaping the ... facility." In exchange for not suing the infiltrator for illegally filming within Covance's lab, PETA US signed an agreement to hand over all video footage and written notes to Covance, and agreed to a ban on conducting any infiltration of Covance for five years. The company filed a parallel lawsuit in England in an attempt to stop PETA showing the tape; the British judge called the footage "highly disturbing", and ruled that there was a legitimate public interest in the material being shown. Covance and PETA agreed to a
