I'm not making good progress with that question. You know I'm not a lawyer, right? The POI presumably has a lawyer to minimize the risk of being charged or if charged, convicted. What the partner's reason would be, I don't know. Perhaps she wants advice on whether she can claim exemption from testifying or avoid questions on a particular topic. But this has ramifications for the POI, and the lawyer shouldn't give the partner advice that would go against his other client's interest. Perhaps she tells the lawyer something that conceivably could be helpful for the POI but she doesn't want him to know. Perhaps her evidence changes under oath and the lawyer wants to walk her back, but how do you cross-examine your own client? The lawyer, knowing more about the case than we do, would be in a better position to think about what sorts of problems might come up, or whether it's clear there's no problem. It could be a long road ahead--not just the inquest. My feeling is that he might give MS a little "support" as part of his service to Spedding, but if she showed any sign of being needed to be treated as an independent client, it would be safer to refer her to someone else.
