I suppose it depends on the criteria being applied. However, at Level 2 and 3 most Law Schools ask for an awareness of the practical implication of the law/a judgment. Example: if a case is set on broadening the rules of consideration in contract law to uphold more agreements to accept less = issue with use of economic duress to procure such agreements = in the post credit crunch era a likelihood of more consumers being allowed to wipe off more debts = impact on business. I also came across a wonderful case analysis recently where the student was able to show how a case would impact on the financial markets. It is original ideas like that with a social or economic angle that can boost marks. However, I take your point - legal impact is key.
