Narrative:
Aircraft #2 was left on radar vector from previous controller (unknown to me). That vector caused aircraft #2 to be in confliction with aircraft #1 on vector. Supplemental information from acn 602786: I was working the RA position at sector 19 during an operational error between air carrier X and air carrier Y. Contributing factors were traffic complexity and volume. Also N90's failure to adhere to our LOA.

Title: ZBW CTLR EXPERIENCED LOSS OF SEPARATION AT FL210 WITH A319 AND B767 APPARENTLY DUE TO N90 NON COMPLIANCE WITH INTERFAC LOA.
Narrative: ACFT #2 WAS LEFT ON RADAR VECTOR FROM PREVIOUS CTLR (UNKNOWN TO ME). THAT VECTOR CAUSED ACFT #2 TO BE IN CONFLICTION WITH ACFT #1 ON VECTOR. SUPPLEMENTAL INFO FROM ACN 602786: I WAS WORKING THE RA POS AT SECTOR 19 DURING AN OPERROR BTWN ACR X AND ACR Y. CONTRIBUTING FACTORS WERE TFC COMPLEXITY AND VOLUME. ALSO N90'S FAILURE TO ADHERE TO OUR LOA.
