I am looking for a word to describe someone who approves or denies something. However, the word must start with a "C". Here is how it is so far:
# CueCreator <-- The person who creates the Cue
# CueCompleter <-- The person who completes the Cue
# Cue? <-- The person who determines whether the Completed Cue is valid or invalid
"CueDECIDER" might be OK in meaning, but the word needs to start with a C. Any ideas?
