Narrative:
My commercial multi-engine certified student was flying the ILS to tiw at night. I was in the right seat instructing and acting as safety pilot. Another aircraft had passed near us several times during the approach and each time seattle approach notified us of his presence. As we approached scenn seattle approach said something like 'there he is again, at your 10 O'clock position, less than 1 mi at your altitude.' we acknowledged that we had him in sight. He was crossing the localizer, passing in front of us from left to right. Then he turned towards us, and I had to take the controls to perform an evasive maneuver that I hoped would take us around behind him. We established ourselves again on the localizer and glide path when the other aircraft dove down on us from above and behind, cutting us off of our final approach. The pilot of the other aircraft said that he was announcing his intentions all the time on the common frequency and implied that this exempted him from the right of way rules and from the duty to see and avoid.

Title: NMAC BTWN A C172 ON AN ILS APCH AT 5 NM TO RWY 17 AND A VFR ACFT IN THE PATTERN FOR SAME RWY DURING A NIGHT OP AT TIW, WA.
Narrative: MY COMMERCIAL MULTI-ENG CERTIFIED STUDENT WAS FLYING THE ILS TO TIW AT NIGHT. I WAS IN THE R SEAT INSTRUCTING AND ACTING AS SAFETY PLT. ANOTHER ACFT HAD PASSED NEAR US SEVERAL TIMES DURING THE APCH AND EACH TIME SEATTLE APCH NOTIFIED US OF HIS PRESENCE. AS WE APCHED SCENN SEATTLE APCH SAID SOMETHING LIKE 'THERE HE IS AGAIN, AT YOUR 10 O'CLOCK POS, LESS THAN 1 MI AT YOUR ALT.' WE ACKNOWLEDGED THAT WE HAD HIM IN SIGHT. HE WAS XING THE LOC, PASSING IN FRONT OF US FROM L TO R. THEN HE TURNED TOWARDS US, AND I HAD TO TAKE THE CTLS TO PERFORM AN EVASIVE MANEUVER THAT I HOPED WOULD TAKE US AROUND BEHIND HIM. WE ESTABLISHED OURSELVES AGAIN ON THE LOC AND GLIDE PATH WHEN THE OTHER ACFT DOVE DOWN ON US FROM ABOVE AND BEHIND, CUTTING US OFF OF OUR FINAL APCH. THE PLT OF THE OTHER ACFT SAID THAT HE WAS ANNOUNCING HIS INTENTIONS ALL THE TIME ON THE COMMON FREQ AND IMPLIED THAT THIS EXEMPTED HIM FROM THE RIGHT OF WAY RULES AND FROM THE DUTY TO SEE AND AVOID.
