I know that, but Dr. Byrne cited Covid as the reason. I am asking in what way Covid played a part. Was it that individuals were contacting the SEAI and saying they did not want the work carried out? Was it that contractors were refusing to carry out the work? Was it a direction by the SEAI that the work not be carried out?
