Q. (See questions 2771- 75 above - regarding fences separating backyards for the purpose of having a minyan), When there is a mechitza, and you can't repeat shemonezreih, can you do Kerias Hatorah?
A. As mentioned in question 2771 above the reading of the Torah is similar to the repetition of the amida and requires a proper minyan. See Megila 23b that it is included in the mitzva of "Venikdashti Betoch Bnai Yisroel" (I will be sanctified amidst the Bnai Yisroel). Ran (ibid.) asserts that it is a decree of the Sages.
Horav Shlomo Miller's Shlit'a opinion is that it is akin to the repetition of the amida, since it involves a brachoa levatala (blessing said in vain), as opposed to kaddish and kedusha, and one should be more stringent.
