Decreed dramatically? (7)

I believe the answer is:
enacted
'decreed dramatically?' is the definition.
Although both the answer and definition are past participle verbs, I can't understand how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for enacted that I've seen before include "Ordained" , "Performed as in a play, or passed into law" , "Made a bill into law" , "Passed legislation" , "Put into practice" .)
