Is one of the first administrative remedies, and I love it.

I have used on documents that were "personally served" by a process server - for a "default hearing". This type of hearing they "request" you bring in all your financials so they (child extortion agency) can take them. The "penalty" can be jail as an outcome of the "default hearing".

Refused for cause. returned via regular mail within 3 days of delivery.

Funny thing about RFC. How does one provide evidence of something that doesn't exist ?
