Narrative:
Aircraft #1 was level at FL350, filed as an IL62/west, aircraft B was an L101/west, climbed to FL340 underneath with no time crossing non radar. After looking at the flight plan of air carrier X, I noticed that he did not enter mnps airspace. I asked the flight if he was rvsm and mnps certified. He replied 'negative' meaning 1000 ft vertical separation was not legal.

Narrative: ACFT #1 WAS LEVEL AT FL350, FILED AS AN IL62/W, ACFT B WAS AN L101/W, CLBED TO FL340 UNDERNEATH WITH NO TIME XING NON RADAR. AFTER LOOKING AT THE FLT PLAN OF ACR X, I NOTICED THAT HE DID NOT ENTER MNPS AIRSPACE. I ASKED THE FLT IF HE WAS RVSM AND MNPS CERTIFIED. HE REPLIED 'NEGATIVE' MEANING 1000 FT VERT SEPARATION WAS NOT LEGAL.
