A more thorough explanation:

A bathtub conspiracy is a type of intra-enterprise conspiracy, which refers to a conspiracy existing between two subsidiaries, divisions, or other parts of the same firm. In other words, it is a conspiracy that takes place within a company or organization.

For example, if two departments within a company conspire to cover up a mistake or wrongdoing, that would be considered a bathtub conspiracy. The employees involved in the conspiracy would be working together to achieve an unlawful objective, which is to hide the mistake or wrongdoing from others within the company or from the public.

It's important to note that conspiracy is a separate offense from the crime that is the object of the conspiracy. This means that even if the unlawful act is not carried out, the conspiracy itself is still a crime.

Overall, a bathtub conspiracy is a type of illegal agreement that takes place within a company or organization, where employees work together to achieve an unlawful objective.
