Ms Velma Burns:

Of the 52 cases where no toxicology report was available, this does not mean that no toxicology test was taken, but that at the time of the analysis of the data collection, a toxicology report was not available in the file. However, there was significant and strong evidence in the file that confirmed that alcohol was a factor in the collision. That may come from, say, a garda opinion, a witness statement or other strong evidence in the file. As I mentioned earlier, somebody might have said that he or she was with the person all afternoon, drinking in the pub and he had consumed a certain number of pints. There was strong evidence in the file and each file was reviewed on a case-by-case basis to ensure that it was validly included as an alcohol-related collision.
