During his time in the Government Offices, he worked, among other things, on drafting a new Swedish constitution, which transformed the Riksdag from a bicameral legislature into a unicameral one.
[4] Lidbom was assistant teacher in law at Stockholm University from 1959 to 1965[1][2] and served as an expert in negotiations, among other things in the Council of Europe and in the International Labour Organization from 1961 to 1965, and as an expert in the Constitutional Preparation (Grundlagberedningen) and in Tax Punishment Law Inquiry (skattestrafflagutredningen) from 1966[1] as well as the County Democracy Inquiry (Länsdemokratiutredningen).
[3] Lidbom was known in certain circles by the nickname "Calle Batong", and his tough legislative approach also gave rise to the term "Lidbomeri," which refers to hastily drafted laws often driven by political motives.
With the help of his close friend Ebbe Carlsson, a book publisher but also a private investigator, Lidbom began to examine the so-called PKK lead.
In 1988, Expressen reporter Per Wendel exposed the collaboration and dubbed it the "Ebbe Carlsson affair," triggering a political scandal that forced Justice Minister Anna-Greta Leijon to resign.
