Talmud Yerushalmi Halachot

Question

The halacha we have today is mostly sourced in Talmud Bavli(the Babylonian Talmud),Medrash and Zohar. I would like to know what Halachot which we have today which are sourced strictly in the Yerushalmi (the Jerusalem Talmud) and where they can be found in the Yerushalmi. Any Halacha would be appreciated.

Answer 1

The answers to this question refer to a Yerushalmi (Shabbos 7:2) that extends the melachah of זורה (winnowing) to scattering something in the wind (the example given is spitting). This is cited as halachah in Rema, Orach Chaim, end of sec. 319.

Answer 2

The Shulchan Aruch rules in OC 448:6 that you can't feed chametz to an ownerless animal based on Yerushalmi Pesachim 2:1

Answer 3

From the Rabbi Broyde post that I referenced in a comment to your un-duplicate question:

Consider, for example, four examples that I happen to have written about or am writing about currently—tefillin on Chol ha-Moed, aliyot in a city where all the men are kohanim, whether the daughter of a gentile man and Jewish woman may marry a Kohen, and the of using charity funds to build synagogues rather than to support the poor.

In all four cases, the Bavli is silent while the Yerushalmi directly addresses the matter. On the topic of tefillin on Chol ha-Moed, Y.Moed Katan 3:4 is clear that tefillin should be worn; in Y.Gittin 5:9 it is clear that even in a city where all the men are kohanim, women do not get called to the Torah; Y.Yevamot 4:15 is clear that such a woman cannot marry a Kohen; and in Y.Peah 8:8 it is clear that a synagogue is a valid recipient of charity. Although it is obvious that each of these four matters generates some controversy among the Poskim, I suspect that the core dispute is whether one needs to adopt the halachic norm as expressed by the Jerusalem Talmud. Much more could be written on this matter.

Answer 4

So so so many laws of zeraim as there is no bavli on that order of mishna.

[I know this isn't specific, but I wanted to put it out there]

Answer 5

In Hilchot Mezuza (Yore Deah 285) the Rama rules off the Yerushalmi that if one can only buy Tefilin or Mezuza, he should buy Tefilin (the end of Megila in Yerushalmi- exact source BN coming soon).

Answer 6

According to the Yerushalmi (Megillah 1:9), letters in Sta"m need to be mukaf gevil (surrounded by white parchment) on the inside of the letter as well (eg a the inside of a samech). See Shulchan Aruch OC 32:15
