First established at the International Penitentiary Congress of London in 1872, the International Penal and Penitentiary Commission was organized as it now exists by constitutional regulations adopted in 1880, confirmed in 1886, and revised in 1926, 1929, 1946 and 1948. Eleven international congresses have been convened, the last in Berlin in 1935; and the commission held its most recent meeting in Bern in August of 1949. The commission took as its terms of reference responsibility for promoting exchanges of views among expert penologists of all countries in order to develop standards and advise as to the development of progressive methods of preventing crime and treating offenders: The expenses for 1949 were estimated at 121,400 Swiss francs ($28,365), payable by the members at a ratio of 170 Swiss francs ($39.64) per one million inhabitants. By a resolution of October 16, 1948, the commission and other major international organizations concerned with the prevention of crime and treatment of offenders agreed on the various aspects of the field in which each would work and on cooperation with the United Nations. ILO, WHO, and UNESCO were among the specialized agencies which agreed to the resolution. A later resolution on cooperation with the United Nations, adopted by the commission in August 1949 was reviewed by ECOSOC which, in turn, requested the United Nations Secretary-General to coatinue consultations with IPPC with a view toward its integration in the United Nations system.
