Q. How many times does one have to have davened Tefilas Geshem for the amud, to be considered that he has a chazaka, and he has a right to demand he davens before anyone elase?

A. Horav Shlomo Miller’s Shlit’a opinion is that in a shul were there is no official chazan or baal tefila, a chazaka of three years of consecutive davening may be required to give first rights to a shalich tzibur. However, the Rov pointed out that there may be other preestablished takonos and conditions that a shul may have adopted.
