There are other aspects of the question that might be dwelt on at some length, if this were the proper occasion. Since it is recognised in all parts of the House that a great measure is not and cannot be adequately discussed under the guillotine closure, a dangerous practice has grown up of leaving difficult matters to be decided by Government departments or by new authorities set up under the Act. Under the National Insurance Act, for instance, the Commissioners are invested for certain purposes with all the legislative prerogatives of the three estates of the realm! I must leave that matter to the constitutional authorities. I am concerned for the moment merely to show that the guillotine closure is a clumsy, unbusinesslike, and dangerous expedient that cannot be regarded as having solved in any satisfactory degree the eternal problem of congestion in a Parliament that attempts to cope at the same time with the local affairs of three or four provinces, and with the affairs of an empire. Relief might doubtless be found in the more frequent use of what is known as the “kangaroo” closure. This method of dealing with business in Committee was first regularized in 1908. Under this system, power is given to the Chairman to select such Amendments as he believes to be really important, to the exclusion of others. The burden of responsibility thus thrown on the Chair is felt to be enormous, and it is chiefly on this account that the kangaroo closure has been very sparingly exercised.
