Law is a popular course, and is not usually in clearing. There's no guarantee any course at Leeds will be in clearing. Note that universities don't take rejections lightly, if they could have offered you a space, they would have. Your rejection should be seen as an indication to the incredibly stiff competition for law this year, and it will unlikely be in clearing.
A less popular course is criminology, which might or might not be in clearing.
Edit: nvm, try looking at another university. Leeds is not in clearing at all for any subject this year; they have filled their spots.
