asked the Secretary for Mines the number of complaints that have been dealt with by the National Committee of Investigation set up under Section 5 of the Coal Mines Act, 1930; and in how many cases have the complaints been substantiated?

Two complaints have been lodged with the National Committee of Investigation since it was set up in 1930. One complaint lodged in March, 1931, was rejected by the committee. The other complaint, lodged about two weeks ago, is under investigation.
