Thank you very much for your reply.
I might have been the one who got the reasons for refusal wrong, as I had already written here before I had all the facts. My apologies.
My brother in law said that the refusal was based on him having £13,200 (excluding his school fees which if added to his account would come up to £18,000)on his statement, and 10 points was deducted from his points. I'm afraid I don't know how the point based situation is calculated, but his argument was that he was suppose to have £15,000. He argued that they disregarded his school fees which was suppose to be part of it. Now I don't know if that is the case, I'm going by what he told me. That is the first reason.
The second reason for refusal according to him was that when he entered this country to get his maters and then when he wanted to do another course unrelated to what he studied was told he had the option of working his way up, so he started from the beginning as a student working his way up to this level (again I don't know what this means) but the refused saying that he had already reached this level, he is saying that they gave him this option in the first place, meaning that he can forgo his first masters as it doesn't count to the type of visa.
He has been given 10days to appeal instead of 28days so, all these is a bit complicated and he believes and insists that he met every requirements. so has a case for appeal?
