"It seems that the name Babri Masjid became the official term from this report onwards, as before it was mostly referred to as Masjid-i Janmasthan... It is even disputed whether the Masjid was effectively used before 1934, and even before 1855. ... What is more, neither [Joseph Tieffenthaler] nor, to my knowledge, any of the Muslim sources, mentions Muslim worship in the Babri Masjid. These are indications for what many common people in Ayodhya have told me : that the Babri Masjid has not been a real mosque for most of its history. With such a prehistory, it also becomes understandable that the local Muslim community in the 1930s and 1940s could have a mosque standing there and yet not use it... on the strength of local Muslim testimony, the Babri Masjid was not in regular use since at least 1936. If any firm counter-proof had come up by now, I guess we would have seen it: the pro-Babri faction has enough media at its disposal to present the strong points in its case."
