Please Help Someone!!!

If someone has watched the film: "Class Action" (1991) could I receive some help in answering these questions below, please? Here is the link to the reference:

The movie focuses on an alleged commission of a tort by a car manufacturer, what is often known as a "product liability" action.

2) At some point, the defendant's law firm decides to disclose the test results showing the defect in thecar but buries it along with thousands of other documents in the documents they turn over to the plaintiff's law firm. The defendant firm's managing partner decides it is within the letter of the law.

a) For each ethics rule/test from the W-H framework on pp. 23-27, make an argument that the action, while legal, may be unethical. Make sure that for each rule/test you identify at least two groups of stakeholders from the framework that could be affected by the law firm's activities and provide support for a reason why they might feel it would be unethical under the rule/test. b) The defendant does an actuarial analysis (risk management calculation) of the losses they might incur due to lawsuits over the defect and the cost of the recall and retrofitting. Complete an ethical analysis of that actuarial analysis that resulted in them not fixing the car. To do this, analyze each set of stakeholders on p. 23 and identify which ones stood to benefit or not benefit from that decision.

The reference to the movie is the link above but if you can find the answers through an online website than that works as well.
