Narrative:
The captain started the descent into cyyc at the top of descent for the altitudes that were programmed into the FMGC. Were initially cleared pilot's discretion to FL240. Soon after starting the descent we experienced an ECAM for a failure of the hp valve 2. The cabin descent rate increased as the pressurization tried to deal with the issue. I dealt with the ECAM and the captain slowed the rate of descent to help slow the rate of descent of the cabin. We were switched to approach at some point and given a 'descend and maintain 10;000.' we were above profile at this point and I mentioned that we still needed to make the altitude restriction at ebgal. The captain responded that that was not the case since we had received a descend and maintain clearance. We had a brief discussion about it and he queried the controller what speed he would like at ebgal though not what altitude. I assumed that I had misread the recent changes and rescinding of said changes incorrectly as we discussed it. In retrospect; I should have just queried ATC or asked for relief on the published constraints. We ended up crossing ebgal at about 15;000 ft. Instead of at or below 14;000 ft.

We were above profile at this point and I mentioned that we still needed to make the altitude restriction at EBGAL. The Captain responded that that was not the case since we had received a descend and maintain clearance. We had a brief discussion about it and he queried the controller what speed he would like at EBGAL though not what altitude. I assumed that I had misread the recent changes and rescinding of said changes incorrectly as we discussed it.
