Under Pennsylvania's Child Protective Services Law, certain individuals, including teachers and school administrators, have a legal obligation to immediately report suspected child abuse to child protective services or law enforcement, or to a "person in charge" (supervisor), who must then report the alleged abuse to the authorities. The reporting must be honest. When in writing, the reporting must also include known information about the nature and extent of the suspected abuse, along with other material details.
Within one day of learning from McQueary of the alleged abuse, Paterno notified Curley, his boss. By doing so, Paterno satisfied an obligation to immediately report to a person in charge.
On the other hand, one could read the Child Protective Services Law to classify Paterno as himself a person in charge of McQueary and as one who had a subsequent obligation to report to the authorities. Still, Curley's status as Paterno's boss likely insulates Paterno from liability, at least for failing to notify child protective services or law enforcement.
Paterno may have nonetheless violated the Child Protective Services Law by failing to tell Curley the specific story as told by McQueary and by failing to provide known information about the nature and extent of the suspected abuse. As discussed above, if McQueary's testimony is true, Paterno appeared to downplay the severity of the incident while speaking with Curley. His portrayal seemed incomplete, if not outright disingenuous. Also, while Paterno made his initial report of the suspected child abuse to Curley by phone, any written communications would have required the known information.
