In practice, many sales contracts do not specify what needs to happen in the case the objective for which a genetic resource is provided changes. Like many other issues, the debate at Nagoya took place over largely North-South lines and the text of the Protocol avoids providing a clear answer to this question. Up until 12 October 2014 when the Protocol comes into force, genetic resource transfers to outside the provider country in fact continue to be pre-Nagoya (in the absence of Nagoya-compliant ABS legislation). Plants that are part of ex situ collections or animals that reside in zoos are examples of such genetic resources.
