I am teaching ethics in a statistics class. I am looking for examples when deceptive statistical evidence was caught or attempted to be used.

For example, is there an example of a party who had several surveys or studies performed and tried to only publicize the findings that was beneficial to them?

I am looking for court case examples. Thank you.

Edit

I am aware that using misleading statistics can be punished by being fired or publicly disgraced in the scientific community, which is not a legal matter. However, some statistics is actually used for important decisions or claims. I am looking for when bad statistics contributed to a decision that caused damages that led to a criminal or civil case.

I am not part of the law community, so I cannot say whether I am looking for fraud, bad faith, or incompetence in any technical sense. But here is an example.

Say a company pressured researchers to conclude a product was safe or exceeded its true capability. Then that product caused damage to some party who sued. If evidence came that a biased sample was purposefully used, I think that would show bad faith on that company and have bearing upon the court's decision. Or if a too small sample was taken and the data was presented without confidence intervals, that could show *incompetence* and the company failed to perform due diligence.

Outright falsification of evidence would clearly show unethical practices, but I am looking for more interesting examples in the "grey area."

I did not find any case examples, so I assume there are not many. That is why I asked it here.
