【单选题】In the case of International Primate Protection League vs Institute for Behavioral Research in the US, what of the following events never happened?
A.
In 1981, a graduate student & PETA member, Alex Pacheco, volunteered at a research center in Silver Spring, Maryland. At the time, Edward Taub was conducting research on monkeys for neuroplasticity purposes at that center.
B.
While Alex spent time at the research center, he noticed the inhumane treatment of the monkeys under the AWA and reported it to the police. He filed suit against Edward Taub, who was researching afferent ganglia. Edward Taub was convicted of six animal cruelty charges, which were appealed in the second trial. They proved to be significant in the understanding of the law.
C.
While this case provided an advancement in neurology research, it was at risking inhumane treatment of animals. As the court wrote in its opinion: "To imply a cause of action in these plaintiffs might entail serious consequences. It might open the use of animals in biomedical research to the hazards and vicissitudes of courtroom litigation. It may draw judges into the supervision and regulation of laboratory research. It might unleash a spate of private lawsuits that would impede advances made by medical [sic] science in the alleviation of human suffering. To risk consequences of this magnitude in the absence of clear direction from the Congress would be ill-advised. In fact, we are persuaded that Congress intended that the independence of medical research be respected and that administrative enforcement govern the Animal Welfare Act."
