The Wilkes/Gleditsch trial (Norwegian: Wilkes/Gleditsch-saken[1]) in 1982 in Norway, involved two "researchers' (of Peace and conflict studies) publication of a research report on electronic listening stations, based on information from open sources. Putting the information together into a complete picture was judged to reveal a secret according to the "puslespill doctrine», cf the website of Norway's Cabinet in 2011.[2]
Electronic listening posts[3] in North-Norway, and their significance was the secret that was revealed.[4] (The Wilkes/Gleditsch case has been mistaken/confused[5][6] with the "Loran C affair", that concerned the publication of the existence of a radiowave-transmitter used for navigation.[7])
Owen Wilkes and Nils Petter Gleditsch were convicted of breaching a Norwegian criminal code, pertaining to national security — paragraphs 90 and 91 of Straffeloven. They received a suspended prison sentence, in addition to being fined and charged with court costs.
The trial has various other names in Norwegian, including "Gleditsch-saken", "Gleditsch/Wilkes-saken", and "kaninsaken" (the rabbit trial).
