Sanhedrin in Tiberias II

"In our time, after the establishment of the State of Israel, the question of renewing the Sanhedrin was raised by R. Yehudah L. Fishman-Maimon and the view of the giants of Torah in Israel and the exile is - for whatever reason - not to reintroduce semikhah [the original ordination required for a Sanhedrin]."
- R. Menahem M. Kasher, Torah Shelemah, vol. 15 p. 200

"It is clear in the Rambam - 'And all the laws return to as they were earlier' [Mishneh Torah, Hilkhos Melakhim 11:1] - that he rescinded his words from his commentary on the Mishnah and is of the view that Mashiah must come before the Sanhedrin [is renewed]."
- R. Menahem M. Kasher, Ha-Tekufah Ha-Gedolah, vol. 1 p. 378
