England a document had to be in a party's sole legal
possession for an order to be made for its production. The
reason for this was that the power of the court or judge was
to order the production by any party of such of the
documents 'in his possession or power', relating to any
matter in question in the cause or action. It has been held
in relation to the old practice that possession or power for
the purpose of justifying an order for production had a
narrower meaning than for the purpose of inclusion in an
affidavit of documents. 'Possession or power' for the
purpose of an order for production means sole legal
possession, a right and power to deal with them: see
Kearsley v Philips (1882) 10 QBD 36; 465; Murray v Walter
(1839) Cr and Ph 114; [1839] EngR 983; 41 ER 433; Coomes and Son v Hayward
(1913) 1 KB 150. Thus, whilst it was necessary to include
in an affidavit of documents all documents in which the
party had any possession or property jointly with others or
even in which he had no property at all if they were in his
corporeal possession, the court would not order such
documents to be produced. It was sufficient for the party
concerned to state that a document was not in his sole legal
possession and it was not necessary for him to allege or
show the refusal of the co-owners to produce: Kearsley v
Philips (1882) 10 QBD 36; 465; but he was required to state
their names and the nature of their ownership: Bovill v
Cowan (1870) 5 Ch App 495. Under the old practice that was
the end of the matter as the court had no discretion in the
face of the assertion that the party concerned did not have
sole legal possession It is, I think preferable to say that
documents falling within this category were protected rather
than privileged from production.
However, the introduction of Supreme Court Rules, O 24
widened the scope of the court's power to order production
for inspection and thus, the obligation of a party to
produce: see Supreme Court Rules, O 24, r 7. This rule
together with O 24, r 12 extended by the inclusion of the
word 'custody' the previous power of the court to order
inspection as these documents were no longer automatically
protected from production for inspection .....
Prior to the introduction of the Supreme Court Act, 1970 and
the rules made thereunder - see Pt 23, rr 7, 8 and 10 - the
Supreme Court in this State followed the pre 1964 English
Practice in relation to discovery and inspection. However,
whilst s 102(1)(b) of the New South Wales Common Law
Procedure Act 1899 required a party to state on affidavit
what documents he had in his possession or power, it was not
encumbent upon him to state what documents he also had in
his custody. However, Pt 23, rr 7 and 10 of the present
rules include the word 'custody' and thus, a party is
obligated now to produce for inspection documents of which
he is part owner or of which he has custody as a servant or
agent for a third party who owns the document. ...
The position is that once again the New South Wales Practice
is in accord with the English Practice. I say this despite
note 23.6.5 (c) and (d) to Pt 23, r 6 of the New South Wales
Supreme Court Rules that documents thought relevant and
thus, disclosed in the list of documents are 'privileged'
from production if they're not in the sole possession of the
party giving discovery or are in the possession of a party
only as agent for or on behalf of another."
