17   Giving, modifying and revoking consent

(1)  A gamete provider may give an ART provider that obtains, or proposes to obtain, a gamete from the gamete provider a written notice setting out the gamete provider’s wishes in relation to the gamete (the gamete provider’s consent).

(2)  A gamete provider’s consent may address such matters as the uses that may be made of the gamete (or an embryo created using the gamete) and whether the gamete or embryo may be stored, exported from this State or supplied to another ART provider.

(3)  A gamete provider may modify or revoke his or her consent by giving written notice of the modification or revocation of consent to the ART provider:

(a)  that obtained the gamete from the gamete provider, or

(b)  that is in possession of the gamete or embryo to which the modification or revocation of consent relates.

(4)  A consent may be modified or revoked at any time up until:

(a)  in the case of a donated gamete—the gamete is placed in the body of a woman or an embryo is created using the gamete, or

(b)  in the case of a gamete other than a donated gamete—the gamete is placed in the body of a woman or an embryo created using the gamete is implanted in the body of a woman.

(5)  Modification or revocation of consent takes effect in relation to an ART provider as soon as the ART provider is given written notice in accordance with this section.

(6)  As soon as practicable after being given written notice in accordance with subsection (3) (whether by a gamete provider or by another ART provider) an ART provider must give written notice of the modification or revocation of consent to any other ART provider to whom the first ART provider has supplied the gamete or any embryo created using the gamete.
