It is worth quoting their terms of reference in full.

If the terms of reference haven't changed, the landscape in which they are applied certainly has.

The terms of reference for this review are also below.

The terms of reference for the Commission were extended twice.

The terms of reference were set by him and he failed to meet them.

He added that the terms of reference for the review had not yet been decided.

However, the terms of reference were not extended to include the fire.

And the terms of reference would appear to me to be obvious.

I have great respect for their work, within the given terms of reference.

But that is the problem: they are forced to work within the given terms of reference.
