The families of those victims have campaigned tirelessly to reveal the truth of what happened during the FA Cup semi-final in Sheffield in April 1989.
And after a public apology was issued in parliament earlier in the week McCoist is hopeful those families can now find some peace.
McCoist said: “The timescale is horrendous for the families. I remember the day it happened, we were playing St Johnstone at Celtic Park in a cup tie.
“It was horrendous then and to think that the families haven’t had any closure on it for that period of time in itself is probably the biggest injustice of the lot.
“The one thing that must come out of the whole process is that the families get clearance and closure on the issue because that’s what they and the deceased deserve.
“It must get resolved because it’s tragic that it’s come to this point.
“Twenty three years is an outrageous period of time for families not to have closure on something of this magnitude.
“Although the most important thing is that they get that closure, you would hope that comes sooner rather than later because it’s been a long, long time. Too long."
