Einar Høgetveit (1949–2020), who was educated in law from the University of Oslo, joined PRIO in 1978 on a project to compare legislation and practice concerning national security. Specifically, he scrutinized the US Freedom of Information Act of 1966 (substantially strengthened in 1974 in the wake of the Watergate scandal) and the Norwegian Public Access Act (Offentlighetsloven) from 1971 as well as other relevant legislation relating to openness and secrecy. He confirmed the widespread impression that the US legislation mandated greater openness, but also demonstrated the importance of administrative practice.

Following his period at PRIO, Einar Høgetveit worked on a study of Sami rights,

next in the Norwegian Ministry of Justice. Later, he joined the Norwegian National Authority for Investigation and Prosecution of Economic and Environmental Crime (Økokrim), which he headed in 2000–09. He finally served as a judge in the Borgarting Court of Appeal.
