Answer:
13. Charlie would be excluded for cause;
14. the plaintiff provides proof only up to the level of “clear and convincing,” Casey can still be acquitted.
Explanation:
Since it was realised that Charlie has a relationship with on of the parties summoned for a case, this will lead to Charlie been removed and excluded for cause. This is because it is believed that due to the fact that he has a relationship with the person, there may be bias which may lead to a false outcome regarding the case.
For the second question, Cash can be acquitted if there's proof which is provided by the plaintiff and the proof is clear enough and convincing.
