McTiernan J. The circumstances under which the University of
Birmingham and the Epsom College respectively came to be entitled to
receive the Australian income which is the subject of the assessments
made by the commissioner and the constitution and objects of each
institution are set out in detail in these cases, which have been stated
by Rich J. These cases raise the question whether the income is
exempt from taxation under sec. 23 (e) of the Income Tax Assessment
Acts 1936. It is not disputed in these appeals that the constitution
and objects of each institution bring it within the list of institutions
set out in sec. 23 (e). The question in controversy is whether the
provision of the Income Tax Assessment Acts is limited in its operation
to institutions which are established or carry on activities in Aus-
tralia. If sec. 23 (e) were read without any limitation, it would
extend to exempt from taxation the income of any religious, scientific,
charitable or public educational institution, wherever it is situated.

provision applies without any restriction based on locality, it would
give a wider exemption than Parliament intended ; and the criterion
which he suggests for limiting its operation is based on the presump-
tion which sec. 21 (b) of the Acts Interpretation Act requires, unless
the contrary intention appears, to be employed in the interpretation
of the Act. The words, " which is not exempt income," at the end
of sec, 25 clearly include the income which is the subject of the
exemption contained in sec. 23 (e). These words incorporate that
provision in the definition of assessable income in sec. 25, and that
section expressly includes within the definition of assessable income
the Australian income of a non-resident and the non-Australian
income of a resident. The intention of the Act is that, when a
question arises whether the income of an institution is assessable
income, the words, " which is not exempt income," at the end of
Sec. 25 should be read as meaning "which is not the income of a
teligious, scientific or public educational institution." In such a
case these words would have as their antecedent the income of the
institution sought to be taxed, whether the institution was within
