Parliamentary committees are able to summon experts for committee meetings, and they do it regularly and to an increasing extent. A committee starts its work by hearing experts; each committee decides which experts to call in a particular matter. Besides ministerial representatives, further persons, who have assisted in preparatory work or speak for agencies, organizations and other interested parties of importance for the issue, are involved. The scope of hearings varies greatly. In some cases only one expert may be called, but in major legislative projects a committee may hear even dozens of experts.
Data from earlier research show that the committees consulted advisers in 1938 in 59% of all cases on which they prepared reports; the corresponding figure was 94% in 1960 and a full 100% in 1983. The number of experts consulted has likewise been increasing.
