I´ll handle this complaint as its a complaint against the CCIA Lead.
Let's start out with the initial IR:
First of all: I have not checked the logs of the round and I assume that what has been mentioned in the interviews/IR are actually facts. If that is not the case let me know.
I believe that a reprimand for giving a PAI a law to "annoy" a single crew member ("Annoy Imogen Janse") is relatively mild punishment and it might have led to a whitelist removal if ahelped.
In my opinion it is generally under the XOs purview to decide how to operate the Service department (if there is a fee for all or certain items or if certain items are served or not).
However, I do agree with CCIA to curtail that authority if a specific XO shows poor judgement (in that regard).
As such I believe the following reprimand to be warranted:
Let's continue with the appeal:
The first part to look at before posting in a subforum are the relevant subforum rules.
In those subforum rules it is stated that this is a IC Format where your character appeals their punishment with a higher authority.
With that in mind I have to agree with what bear said:
Generally speaking, there are the following levels of IC Action by HR/CCIA:
Informal Warning/Notice
"Flavour Punishment" (i.e. "awareness training, ..."
Reprimand
(Temporary) Demotion
optional: Suspension / other temporary removal from the ship
Termination / Arrest / other permanent removal from the ship
As you have already received a Reprimand and doubled down by sending "a mean letter", the next step is a (temporary) Demotion.
I do not see how getting demoted to janitor after sending "a mean (ic) letter" like you did to CCIA is a "OOC Response to a IC action".
