What does prohibiter mean?
A prohibiter is a person or organization that forbids or prevents something. The word is especially associated with legal, regulatory, and institutional language, where it may identify an authority whose decision makes a restriction binding. For example, a government department can be described as the prohibiter of a particular commercial practice or source of funding. Although the underlying idea is straightforward, “prohibiter” is more formal and less common than words such as “authority,” “regulator,” or “enforcer,” whose meanings depend more heavily on context. It is useful when the emphasis is specifically on the power to forbid rather than on enforcement, punishment, or general control.

"The regulator acted as the prohibiter of practices considered harmful to consumers."

The regular plural is used when referring to multiple persons or bodies that prohibit something.

A prohibiter is not merely someone who says no: in legal and regulatory language, it names the authority whose power makes the prohibition binding.
