Chapter 8: Consideration and Privity
9) Which of the following situations most likely illustrates the concept of pre-existing
public duty not constituting consideration?
a. Pam has threatened to sue Dave for $10 000. She is quite sure that she would win the
case in court. However, because she is very fond of him, she has also generously offered to
settle the matter for $6000.
b. Pam asked Dave, who is a real estate agent, to locate a house in which she could operate
a small accounting business. After he directed her attention to such a house, she promised
to pay $10 000 to him.
c. Pam placed an advertisement in a newspaper that promised to pay $10 000 to anyone
who returned her lost cat to her.
d. In exchange for his promise to pay $5, Pam promised Dave that she would guard a
parking lot in which his car was located during a sporting event. Several minutes later, she
promised Earl, who had also parked there, that she would guard the same parking lot during
the same sporting event if he promised to pay her $7.
e. Pam, who is a fire fighter employed by the city, agreed to extinguish a fire that was
destroying Dave’s house, which is located in the city, only after he promised to pay $10 000
to her in exchange for her services.
10) Parker Inc promised to pay $100 000 cash to Coltrane Ltd in exchange for a shipment
of widgets. The widgets were delivered on October 1st and the price was to be paid on
October 15. On October 13, Parker informed Coltrane that it would not be able to afford to
pay any more than $75 000. Which of the following statements is TRUE?
a. Coltrane will be able to recover the full contract price even if it promises under seal to
accept $75 000 in complete satisfaction of Parker’s debt.
b. Coltrane will not be able to recover the full contract price if it agrees to accept $75 000
from Parker to be paid on October 14 in complete satisfaction of the $100 000 debt, that
was to be paid on October 15.
c. If the parties are located in Alberta, Ontario, British Columbia, Manitoba, the Northwest
Territories, Nunavut, Saskatchewan, or the Yukon, Coltrane will be able to recover the full
contract price even if it has accepted Parker’s offer to pay $75 000 in complete satisfaction
of the $100 000 debt.
d. Coltrane will be able to recover the full contract price even if it accepts Parker’s offer to
satisfy the $100 000 debt by both paying $75 000 in cash and delivering a used truck to
Rollins Corp, which is another company with which Coltrane has close ties.
e. There is no mutuality of consideration, and therefore the contract is invalid, because
Coltrane actually delivered the widgets before Parker was required to pay the purchase
price.
