Immunity of Imamat is among old issues in words of Islamic. Inspite of its abundant emphasises and argumentations and presume as divine office along with prophecy, it is still target of literati's spates and doubts, so that recently Miss Lambton, with the claim of studing historical Shia's thought, try to introduce the issue of Imamat's infallible leaders as lack of historical origin, and presents it as the result of exaggeration in exaggerator's believes. In second century' s recent with a little adjustment gradually has been Shia's dominent thought by Shia theologians. She claims that believe in Imam's immunity couldn't attribute to any Imams, companions f Imams and even the whole Shia in the first century. Analysis of the mentioned claim and it's presented evidence shows lack of true and rational analysis of evolution of Shia's intellectual principle. Its analysis and criticizing shows that she has confused between evolutionary process in Shia's intellectual principle and development in intellectual principle from summary to detail. The aim of this research is to know Miss lambton's confusing and error with disquisition in her words and phrases in the book of government and regimen in Islam. Attaining this aim is feasible in the shade of exact analysis and discription of her words and her orientalist' s fellow with collecting datas in library. The result is proving her's confusing and error in understanding Shia's theology thoughts and its defenders.
