A more thorough explanation:

Aliud simulatum, aliud actum

Aliud simulatum, aliud actum is a Latin phrase that means one thing is pretended, but another thing is actually done.

• A politician promises to lower taxes during their campaign, but once elected, they raise taxes instead. This is an example of aliud simulatum, aliud actum.
• A company advertises their product as eco-friendly, but in reality, it is made with harmful chemicals. This is another example of aliud simulatum, aliud actum.

These examples illustrate the definition of aliud simulatum, aliud actum because in both cases, there is a discrepancy between what is being presented and what is actually happening. The politician and the company are pretending to do one thing, but in reality, they are doing the opposite. This phrase is often used to describe situations where there is deception or dishonesty involved.
