Did Gretchen Wilson infringe the Black Crowes?

Why should this happen? Can someone simply assert that you, the Songwriter, have stolen someone else’s music? Does the fact that someone alleges theft make it a theft? Are you guilty because someone with more (A) power, (B) influence or (C) money (A, B, C, A+B, A+C, B+C, A+B+C) asserts so? Does that more powerful person have any alternate and/or better idea(s)? Has that more powerful person investigated other solutions? What can you, the Songwriter, do? Do you admit to the “facts” with which you have been confronted? Is there a loved one, friend or family member who can help? Do you need emotional help? Do you need financial help? Do you need legal help? Do you need MUSICAL help? Or do you need every kind of help just mentioned and more?
