I have been made redundant.

At appeal I have learned, for the first time that the points awarded to one element of the selection matrix has been changed.

One of the reasons for my appealing was that the points awarded to this element in the selection matrix was unfairly weighted, and unduly determinative.

I feel that the changes my employer has made to this element of the matrix was done only to diffuse this aspect of my appeal, and that the changes were not actually applied to the original selection process, although I cannot prove this.

I was advised that this amendement to the selection matrix did not affect my ranking and my appeal was dismissed.

My question is:

What amendments can an employer make to an already published selection matrix before he is obliged to notify the employees in the redundancy pool of these amendments.
