Translation:Shulchan Aruch/Choshen Mishpat/233

Paragraph 1- If one sells to another one species of fruits and he gives him a different species, there is no sale and either party can retract. How so? If he sold him white wheat and they turned out to be red, or vice versa, or he sold wine and it turned out to be vinegar, or vice versa, or he sold olive wood and it turned out be sycamore or vice versa. If he sold him good wheat and it turned out to be bad, however, the buyer can retract even if there was no overcharge on price, but the seller cannot retract, even if the wheat went up in value. If the seller sold him bad wheat and it turned out to be good, even if he was not overcharged on price the seller can retract, but the buyer cannot, even if the value of the wheat went down. If the seller sold bad and it was bad, or good and it was good, even if it was not the most superior wheat with nothing better or the most inferior wheat with nothing worse, and there is overcharge of 1/6, neither party can retract. Rather, the item would be acquired and the overcharge would be returned. If one sold meat with the understanding that it was a type of castrated ram, and it turns out the ram was not castrated, the sale is valid and the seller would return the overcharge unless it was known that the buyer was finicky and would not eat meat of a ram that was not castrated. The same applies to anything similar. If the seller sold silver with the understanding that it was refined silver, and it turned out to be slag silver, the sale is valid and he would return the overcharge because they are all a form of silver.
