is nothing that I can find in the Constitution to limit " industrial
disputes," in sec. 51 (xxxv.), to disputes between actual employers
and their actual employees. A dispute between a Union and an
employer is much more serious in its effect on industry than a dis-
pute between an individual employee and his employer; and it
would be strange indeed if a dispute of the former kind were to be
treated as outside the purview of the constitutional power. No
doubt, the Act, which was passed under this power, could have
limited the class of disputes to be prevented or settled ; but it has
not done so. By sec. 4, " industrial dispute " means an industrial
dispute extending beyond the limits of any one State and includes
"(1) any dispute as to industrial matters, and (2) any dispute in
relation to employment in an industry carried on by or under the
control of the Commonwealth or a State, or any public authority
constituted under the Commonwealth or a State, and (3) any
threatened or impending or probable industrial dispute." These
words certainly do not limit the class of disputes to be dealt with
under the Act. In the Act as it originally stood, before the amend-
ment of 1911, the only industrial dispute that could be dealt with
(under a plaint), was a dispute to which an organization of employees
is a party; for, under sec. 4, an "industrial dispute " was defined
as one arising between an employer or an organization of employers
onthe one part and an organization of employees on the other part.
The amendment added to, did not subtract from, the class of
industrial disputes. Thereafter it included, for the remedial pur-
poses of the Act, disputes where the disputing employees are not
united in an organization, and disputes which are merely threatened,
impending or probable. There is not the slightest indication of an
intention to take out of " industrial disputes " that kind of indus-
trial dispute which theretofore had been the sole kind of industrial
dispute that could be the subject of a plaint. What, then, is the sub-
ject of the dispute in which the Union is one of the disputing parties ?
The Union insists (inter alia) that any of the respondents who
employs, now or hereafter, any of its members as a boundary rider
shall be forbidden to pay him less than " 40s. per week and found."
This is a dispute of real substance : nothing is so likely to lead to the
stoppage of industry. I need not consider the case of a bystander,
