"It was submitted by Mr Little, on behalf of the applicant,
that the further periods of detention authorised by the
Magistrates were outside their powers and therefore void
and, in consequence, the further detention of the applicant
beyond the first period of the order made on 29 June was
illegal. The submission is based upon the language of
section 38, (3), (3)(a) and (4) of the Migration Act.
In my opinion sub-section (3) of the Act requires a person
to be brought before a prescribed authority for the purpose
of the prescribed authority making an initial investigation.
That investigation is directed to whether there are
reasonable grounds for supposing that the person is a
prohibited non-citizen. In the event of the prescribed
authority being satisfied that there are reasonable grounds
for so supposing, he must then authorise the detention of
the person for a period to enable the Minister to decide two
questions: those question are whether the person is a
prohibited non-citizen and whether a deportation order
should be made in respect of him.
By sub-section (3)(a) the order which the prescribed
authority is required to make under the second limb is
limited to a period not exceeding seven days.
The purpose of detention for that period is to enable the
Minister to decide as a fact or as a question of fact and
law whether the person is a non-citizen, and, furthermore,
whether a deportation order should be made in respect of
him. There are, therefore, two matters for the Minister to
consider. The period of time of the detention of the person
is to enable the Minister to make those two decisions. They
may not be decisions which he is able to make within that
limited period. And so it is under sub-s. (4) the
prescribed authority is empowered to extend the period of
detention.
It was submitted on behalf of the applicant that the period
for the detention in the first place cannot exceed seven
days, and that sub-s. (4) does not enable the extension of
the period to extend beyond seven days from the period of
the authorized detention. It was submitted that accordingly
the total period for which a person may be detained after an
authorization order has been made is limited to seven days.
In deciding the question of construction I have taken into
account the wording of sub-ss. (3) and (4) before the
section was amended by Act No. 117 of 1979. At that time
sub-s. (3) provided:
"The prescribed authority may by writing under his hand
authorise the detention of that person in custody for such
period not exceeding seven days from the date of authorization."
The phrase "not exceeding seven days from the date of
authorization" was removed by the amendments; and
sub-s.(3A) was inserted providing that the period for which
detention in custody of a person brought before a prescribed
authority may be authorized under sub-s.(3) shall not exceed
seven days from the date of authorization or such longer
period from the date of the authorization as the person
consents to. It is seen, therefore, that the amendment
which was effected was by the insertion of the words "or
such longer period from the date of authorization as the
person consents to". In effect the amendment operates to
enable the prescribed authority to fix a period of detention
for a period in excess of seven days if the person consented
to a longer period. Sub-s.(4) was amended by substituting
for the words "the last preceding sub-section" the words "in
sub-s. (3)".
In my opinion, the effect of the amendments is not to limit
the period of detention of a prohibited non-citizen to a
total period of seven days. The effect of it is to enable
the prescribed authority to fix in the first instance a
period of seven days or with the consent of the person
concerned a longer period of time. Furthermore, the
amendment does not detract from the authority of the
prescribed authority to extend the period of detention
beyond seven days."
