Decompilation of computer program by lawful user
239.—(1)  If the conditions in subsection (2) are met, it is a permitted use for a person (X) to decompile a computer program.
(2)  The conditions are —
(a)the program is expressed in a low‑level language;
(b)X is a lawful user of the program;
(c)the decompiling is necessary to obtain the information needed for the purpose of creating an independent computer program that can be operated with the decompiled program or another computer program;
(d)the information needed for that purpose is not otherwise readily available to X;
(e)X confines the decompiling to acts that are needed for that purpose;
(f)X does not use the information obtained from decompiling for anything other than that purpose;
(g)X does not supply the information obtained from decompiling to any person unless it is necessary for that purpose;
(h)X does not use the information obtained from decompiling to create a computer program that is substantially similar in its expression to the decompiled program; and
(i)X does not use the information obtained from decompiling to do any act that is an infringement of copyright.
(3)  In this section, “decompiling”, in relation to a computer program expressed in a low‑level language, means —
(a)converting the computer program into a version expressed in a higher level language; or
(b)copying the computer program incidentally in the course of paragraph (a),
and “decompile” has a corresponding meaning.
