A more thorough explanation:

In rebus means "in things, cases, or matters." It is a Latin phrase used to refer to situations or circumstances.

• When discussing the company's financial situation, the CEO said, "In rebus like these, we need to be cautious."
• The lawyer advised his client, "In rebus of this nature, it's best to seek legal counsel."

These examples show how the phrase "in rebus" is used to refer to specific situations or circumstances. The CEO uses it to caution against taking risks during difficult times, while the lawyer uses it to suggest seeking professional help in legal matters.
