Narrative:

I took the handoff on air carrier X; at FL180; established on swede 1 arrival. Adjacent controller subsequently flashed handoff to me on air carrier Y out of FL220 for 16000 ft and called to coordinate a crossing restr of 10 mi south of alb at 16000 ft; and a turn for air carrier X to stela intersection to rejoin swede 1 arrival. These 2 aircraft come from the same controller; so I concur air carrier Z is frequency changed to me; just as the conflict alert activates. I turn air carrier Z to a 180 degree heading (30 degree radial) which I enter in the 4TH line of the data block; so previous controller knows what action I am taking. Air carrier Y is now 10 mi south of alb at FL180 descending to 16000 ft. I call the previous controller; who explains air carrier Y told him late that he would miss his restr; he turned him immediately to a 270 degree heading (60 degree radial); and because the oedp didn't go off; he was not going to pursue a pilot deviation. This is wrong on so many levels. 1) pilot deviation; 2) immediate turn (to save an oe instead of a midair); 3) absolving pilot on frequency (perpetuating the problem).

Title: ZBW CTLR EXPERIENCED NEAR LOSS OF SEPARATION AT FL180 WHEN INTRAFAC COORD FAILED AND FLT CREW FAILED TO COORD/MAKE CROSSING RESTRICTION.

Narrative: I TOOK THE HDOF ON ACR X; AT FL180; ESTABLISHED ON SWEDE 1 ARR. ADJACENT CTLR SUBSEQUENTLY FLASHED HDOF TO ME ON ACR Y OUT OF FL220 FOR 16000 FT AND CALLED TO COORDINATE A XING RESTR OF 10 MI S OF ALB AT 16000 FT; AND A TURN FOR ACR X TO STELA INTXN TO REJOIN SWEDE 1 ARR. THESE 2 ACFT COME FROM THE SAME CTLR; SO I CONCUR ACR Z IS FREQ CHANGED TO ME; JUST AS THE CONFLICT ALERT ACTIVATES. I TURN ACR Z TO A 180 DEG HDG (30 DEG RADIAL) WHICH I ENTER IN THE 4TH LINE OF THE DATA BLOCK; SO PREVIOUS CTLR KNOWS WHAT ACTION I AM TAKING. ACR Y IS NOW 10 MI S OF ALB AT FL180 DSNDING TO 16000 FT. I CALL THE PREVIOUS CTLR; WHO EXPLAINS ACR Y TOLD HIM LATE THAT HE WOULD MISS HIS RESTR; HE TURNED HIM IMMEDIATELY TO A 270 DEG HDG (60 DEG RADIAL); AND BECAUSE THE OEDP DIDN'T GO OFF; HE WAS NOT GOING TO PURSUE A PLTDEV. THIS IS WRONG ON SO MANY LEVELS. 1) PLTDEV; 2) IMMEDIATE TURN (TO SAVE AN OE INSTEAD OF A MIDAIR); 3) ABSOLVING PLT ON FREQ (PERPETUATING THE PROB).
