Abstract
We develop here a microscopical formalism enabling the simultaneous treatment of the two main effects due to electron-impurity interaction: finite electronic life-time and pinning of the CDW phase. It is found that these two effects affect each other in a way which is particularly non-trivial in the strong pinning limit.
