In the sense that you haven't the slightest idea on whether SU have a decent legal position regarding this, you are. As far as I can see, your whole position is based on it being too much hassle for Everton to make any type of legal challenge to this. On the other hand, the other fella (blueblood the solicitor) seems to think that Everton have SU by the balls, which must mean the club could, imminently, mount a legal challenge regarding this whole sorry affair. So one of you is wrong, or both of you are wrong.
My position is simple, and although I might be wrong about what tort is, I simply maintain that SU have probably taken legal advice from a first-class firm, and now are assured that they are not acting outside of the law.
Quite simple really.
