I think this strays a little bit outside my expertise, but generally speaking, you would want to see information sharing agreements specify clearly how the information may be used, and that includes further disclosure. This is a major issue both in the public sector and in the private sector.
I have my contractual relationships with Facebook and Twitter. I give them information about me. They have licence to share that information with third parties that I don't interact with. I don't know what their names are. This is a major concern.
Generally speaking, from the government's perspective, I would think that should be spelled out in a co-operative relationship with the other governments, the other agencies. If they're found to be breaching that relationship, if they're not playing by the rules that have been established, then the government should consider terminating that engagement.
