7. Fruits that were cut down on Shabbos on behalf of a sick person:
The fruit was not yet ripe: One who cuts down an unripe fruit on behalf of a sick person on Shabbos then [that fruit] is forbidden [to be eaten or even moved] by a healthy person [on Shabbos] being that it is Muktzah. [This applies] even if the person was [already] sick from before Shabbos, and one already had in mind from before Shabbos to cut down the fruit on Shabbos.
The reason for this is: because designating [a Muktzah item from before Shabbos] does not help at all by [items that are] connected [to the ground] in cases that it is still growing and ripening on Shabbos.
The fruit is completely ripe: However, if the fruit has finished ripening and no longer will continue to grow, then designating it [before Shabbos] does help [to remove its Muktzah state and allow it to be moved in the above scenario] even though it was attached to the ground [on Shabbos].
One who cooks or does other Biblical transgressions with prior knowledge of the prohibition:
The person who did the transgression: The food is forbidden in benefit for him forever and the pot need kashering.
All Others: It is permitted in benefit immediately after Shabbos, unless Yom Tov falls after Shabbos in which case it may only be eaten after Yom Tov.
Unintentional transgressor of a Biblical prohibition:
The food is forbidden for all on Shabbos and is permitted for all immediately after Shabbos unless Yom Tov falls out after Shabbos.
One who asks a gentile to do a forbidden action on Shabbos whether advertently or not:
See Chapter 325.
What is the law if the forbidden food fell into other foods?
Fell in on Shabbos: The entire food becomes forbidden for others until after Shabbos whether the food was cooked advertently or inadvertently. For the actual cook however if he cooked it advertently then the entire mixture is forbidden for him forever, irrelevant of the ratio. If he cooked it inadvertently then it is forbidden for him until after Shabbos, just like is the law regarding others.
Fell in after Shabbos: Is nullified in majority for the cook in a case that he cooked it advertently on Shabbos.
Is food that had a transgression done to it on behalf of an ill person allowed to be eaten by others?
Done by a Jew: It is forbidden for any other Jew to eat from it on Shabbos with exception to raw meat from a ritually slaughtered animal, and a fruit that was completely ripe and was designated from before Shabbos. After Shabbos all foods are immediately permitted for all
Done by a gentile: Is permitted immediately after Shabbos for all, with exception to foods that were cooked and baked due to them being Pas/Bishul Akum.
If one asked a non-religious Jew to cook for him and if he did so what is the law?
Some rule the food is forbidden for the asker forever.
May one eat in a Kosher restaurant that cooks on Shabbos?
 Admur 318:6
 Vetzaruch Iyun why this is not prohibited to be moved do to that one may come to pick extra fruit on his own behalf, as said in Halacha 6. However regarding why, it should not be prohibited the same way we prohibit fruit [even fully ripened] that was cut by a gentile on Shabbos [chapter 325 Halacha 8], perhaps is because the decree of it falling off on its own does not apply when a Jew took it off.
 As either way it is for them a Davar Sheyeish Lo Matirin.
 As it is considered a Davar Sheyeish Lo Matirin on Shabbos when the mixture occurred, and since it never becomes permitted for him it never leaves this status.
 However, for others or if he cooked it inadvertently the food itself becomes permitted after Shabbos.
