Conflict of roles
The issue with a conflict of roles is not so much whether you personally have a conflict, but whether the interests of the two organisations conflict.
If you have a conflict of roles, you will need to consider whether it is appropriate for you to participate in the decision-making process “on both sides of the table”. You will also need to think about whether you are going to be in a position to fulfil your obligations to both entities at the same time.
If there is a risk that there might be conflicts at some point during the decision-making process, you should discuss your situation with both entities. This gives each an opportunity to consider the risks from their perspective and decide whether they are comfortable with you participating on both sides.
