“the Rambam paskens in accordance with the Yerushalmi over the Bavli in a significant number of places”
The Rambam paskens in accordance with his understanding of the Yerushalmi that often differs from others’ understanding of the Yerushalmi. I’ve sometimes wondered whether he had access to better manuscripts; much of the Yerushalmi is so confusing that different Acharonim come to completely different conclusions regarding what the gemara is talking about.
