I don't see how you can prove particular mutations are tobacco related. DNA can be damaged by viruses, solar radiation, various industrial chemicals, and naturally occurring replication errors. How would you prove this particular mutation was the result of smoking?
I don't see how this research changes anything from a legal perspective. We already knew smoking causes genetic mutations, but we also know people who've never been exposed to tobacco can develop lung cancer.

The aim is to prove that the pattern of mutations in the tumour (which typically contains several hundred mutations in coding regions, more in the whole genome) are caused by smoking.
