3. A. Library books are situated in the library. The owner of the library has the ownership of the library books and people borrowing the books for this library have the possession of books for a short while.
B. The real property in which the tenant is staying is owned by the legal owner of the real property. In short, the legal or the documented proof carrying the ownership of the real property has the ownership of the property. The tenant staying in the real property of the owner has the possession of the property and not the ownership. The tenant is just staying in it and has temporary possession of the real property.
4. Jack has asked for the refund from Sam, but according to the Sale of Goods Act 1908 (Legislation.govt.nz, section 14 (1), 2014), which says that unless otherwise the sale agreement has a different intention, there is an implied warranty that the goods are free from any encumbrances or charge on any third party when the buyer is not declared about it during the contract of sale. This indicates that the seller has to provide a warranty to the buyer if there is any charge from any third party not known to the buyer. By this act, jack can claim full refund from Sam, but Sam also did not know about the computer being as stolen one and he can also claim the refund from the person who sold it to him. However, section 22 (1) mentions that the risk passes along from the seller to the buyer when there is a contract of sale between them unless any such condition is mentioned in it for the warranty and the passing of risk (Legislation.govt.nz, Section 22 (1), 2014). Thus the transaction is open for both to formulate accordingly and if it is mentioned in it, the seller has to provide a warranty.
