Answer:
None.
Step-by-step explanation:
Although no formal contract was made between Lewis and Tuan, about the $ 3,000 payout that Tuan promised Lewis if he won the race, Tuan may be indicted for failing to fulfill his promise to Lewis.
This is because there is a legal term called "moral damages for unfulfilled promise" which states that when a promise is made (even outside a contract) and is not fulfilled, the principle of objective good faith in contracts is violated. Violation of good fpe refers to the unjustified disruption of negotiations between two people and may thus injure an indictment for moral damages.
