Investigators' powers
I322Powers relating to entry to premises

The powers referred to in section 21(4)(a) are—
a
subject to section 26, to enter at any reasonable time any premises which the investigator has reason to believe it is necessary to enter;
b
on entering any premises by virtue of paragraph (a), to take—

any other person authorised by the investigator and, if the investigator has reasonable cause to expect any serious obstruction in obtaining access, a constable; and
ii
any equipment or materials required for any purpose for which the power of entry is being exercised;
c
as regards any premises which the investigator may enter by virtue of paragraph (a), to direct that—
i
those premises (or any part of them) are; or
ii
any thing in or on them is,
to be left undisturbed (whether generally or in particular respects) for so long as the investigator considers appropriate.
2
An investigator who enters any unoccupied premises in the exercise of a power conferred by virtue of subsection (1)(a) must leave the premises as effectively secured against unauthorised entry as the investigator found them.

The powers referred to in section 21(4)(b) are—
a
to take such measurements and photographs and make such recordings as the investigator considers necessary for the purpose of the public health investigation;

to obtain and to take samples (or cause samples to be taken) of—

any articles or substances found in or on any premises which the investigator has power under section 22 to enter; and
ii
the air, water or land in, on, or in the vicinity of, the premises;
c
in the case of any article or substance found in or on any premises which the investigator has power to enter, being an article or substance which appears to the investigator to be the cause of the public health incident, to cause it to be dismantled or subjected to any process or test (but not so as to damage or destroy it, unless that is necessary);
d
in the case of any article or substance referred to in paragraph (c), to take possession of it and detain it for so long as is necessary for all or any of the following purposes—
i
to examine it (or cause it to be examined) and to do (or cause to be done) to it anything which the investigator has power to do under that paragraph;
ii
to ensure that it is not tampered with before examination of it is completed;
iii
to ensure that it is available for use as evidence in any proceedings for an offence under any enactment or rule of law;
e
to—
i
require the production of (or, where the information is recorded electronically, the furnishing of extracts from) any records which it is necessary for the investigator to see for the purposes of the investigation; and
ii
inspect and take copies of, or of any entry in, the records;
f
to make such examination and investigation as may in the circumstances be necessary.
2
Where an investigator proposes to exercise the power conferred by subsection (1)(c), the investigator must, if so requested by a person who at the time is present on the premises and has responsibilities in relation to those premises, cause anything which is done by virtue of that power to be done in the presence of that person.
3
Before exercising the power conferred by subsection (1)(c), an investigator must consult—
a
such persons having duties on the premises where the article or substance is to be dismantled or subjected to the process or test; and
b
such other persons,
as appear to the investigator to be appropriate for the purpose of ascertaining what dangers, if any, there may be in doing anything which the investigator proposes to do (or cause to be done) under the power.
4
The information which a person may be required to provide under subsection (1)(e) includes information which, although it is not in the possession of that person or would not otherwise come into the possession of that person, is information which it is reasonable to require that person to obtain for the purposes of complying with the requirement.
5
Nothing in this section compels the production by any person of a document subject to legal privilege.
6
A document subject to legal privilege means a communication—
a
between a professional legal adviser and the adviser's client; or

made in connection with or in contemplation of legal proceedings and for the purpose of those proceedings,
which would, in legal proceedings, be protected from disclosure by virtue of any rule of law relating to confidentiality of communications.
I524Power to ask questions
1
The power referred to in section 21(4)(c) is to require any person whom the investigator has reasonable cause to believe has any information relevant to the public health investigation to answer such questions as the investigator considers it appropriate to ask.
2
A person required to answer questions under subsection (1) may nominate one other person to be present during questioning.
3
When a person answers questions under subsection (1), the only other persons who may be present (apart from the investigator) are—
a
the person (if any) nominated under subsection (2); and
b
any person authorised by the investigator to be present.
4
No answer given by a person in pursuance of a requirement imposed under subsection (1) is admissible in evidence against the person in any criminal proceedings.

a
within that person's control; or

in relation to which that person has responsibilities,

The Scottish Ministers may, by regulations, confer on investigators such powers as Ministers consider necessary for the purposes of public health investigations.
