The Doctrine of Severability in the
Judicial Review of Legislation
by
Gerard McCormack, B.C.L., LL.M.
O
UR courts, in exercising the power of judicial review
conferred by the Constitution, have eschewed the
idea that their function is to act as councils of legislative
revision free from restraint. The courts are not the sole
repositories of sagacity nor are they ominiscient and a
number of prudent devices have been fashioned which
limit any oligarchic tendencies on their part. Many of
these have an American provenance
1
and serve to limit the
involvement of the courts in the political process. The
presumption of constitutionality, which has a respectable
pedigree in other jurisdictions creates a bias against a
statute being found unconstitutional and reduces the
impact of the judicial review role on the legislative policy-
making prerogative.
2
The doctrine of separability in the
judicial review of statutes also assists in the achievement
of this objective. The effect was explained by Fitzgerald
C.J. in
Maher
-v-
A.G.
3
"The application of the doctrine of severability or
separability in the judicial review of legislation has
the effect that if a particular provision is held to be
unconstitutional, and that provision is independent
of, and severable from the rest, only the offending
provision will be declared invalid".
Application of the Principle
These observations strongly articulate an idea which
runs through several earlier cases. In
Deaton
-v-
A. G.
A
the
constitutional validity of s. 186 of the Customs
Consolidation Act 1876 was considered. This section gave
the Revenue Commissioners power to select which of two
penalties should be imposed by a Court. The Supreme
Court, overruling Kenny J., held that the "selection of
punishment" was an integral part of the administration of
criminal justice and thus the impugned provision
authorised the impermissible interference with the
operations of the courts in a sphere reserved to them by
the Constitution. However, O'Dalaigh C.J. giving the
unanimous judgment of the Supreme Court stated:
"The Constitution invalidates the section only to
such an extent as it is inconsistent with or repugnant
to the Constitution, i.e., to the extent that the
selection of the penalty is committed to the
Commissioner of Custom (now the Revenue
Commissioners). The section therefore remains
intact with the words at the conclusion of the
Commissioners of Custom (now the Revenue
Commissioners) deleted therefrom."

In
The State (Sheerin)
-v-
Kennedy
6
it was decided that
the power conferred on the Minister for Justice by S.7of
the Prevention of Crime Act 1908 (as adopted) to
determine whether an offender transferred from a Borstal
institution to prison should undergo hard labour or not
was invalid. The section was to be regarded as surviving
but with the offending words deleted. Walsh J. said:
"If there is no essential difference between a term of
imprisonment and a term of detention, then I think
the only portion of the section inconsistent with the
provision of the Constitution is the words "with o r"
following the words "term of imprisonment" the
absence of which would abolish power to commute
detention to a term of imprisonment with hard
labour."

In
The State (C) -v- Minister for Justice
8
the constitu-
tionality of S.13 of the Lunatic Asylums (Ireland) Act
1875 was successfully assailed. Nevertheless.the section
for its want of constitutional
vires
did not fall in its
entirety. The provisions purporting to empower an officer
of the Executive to set at nought the District Court's
remand were excised from the Act and the remainder of
the section survived the offensive unaffected. O'Dalaigh
C.J. said:
"In the result my judgment is that the second part of
section 13 of the Act of 1875 is inconsistent with the
Constitution.. .. This inconsistency can be cured by
the deletion of the words "It shall be in like manner
certified" in line 9 down to the words "and be" in
the fourteenth line of the section inclusive, the rest
of the section being left intact."

The principle of severance has equally been applied
subsequent to the decision of the Supreme Court in
Maher
-v-
A. G.

. In
In Re McAllister
11
Kenny J. was of opinion
that s.385 of the Irish Bankrupt and Insolvency Act 1857,
to the extent that it provided for the commitment of a
person to prison "there to remain without bail", exceeded
the constitutional powers permitted to the legislature. He
added:
"It does not follow, however, that the whole of the
section is repugnant to the Constitution and the
relevant parts of the section should now read
'It shall be lawful to commit such person to
such prison as such court shall think fit, there
to remain until he or she shall submit himself
