From the mid-1980s, Lewis was also Director of Policy Research Associates, working with Conservative and Crossbench members of the House of Lords to initiate changes to legislation (1) requiring postal ballots for trade union elections (incorporated in the 1984 Trade Union Act and 1988 Employment Act); (2) outlawing political indoctrination in schools (incorporated in the 1986 Education Act and carried forward in the 1996 Education Act); (3) prohibiting local councils from publishing material which "promotes or opposes a point of view on a question of political controversy which is identifiable as the view of one political party and not of another" (incorporated in Section 27 of the 1988 Local Government Act); and (4) more strictly defining the concept of 'due impartiality' in the coverage of politically contentious issues on television and radio (incorporated in the 1990 Broadcasting Act).
