"the auditor dismissed her expertise"
Sorry, but an auditor is not there to check on expertise, he's there to check that everything has a trail and the trails all match up to the expenses.
Her complaining about her expertise being dismissed just means that she's pissed that the auditor did not melt before her batting eyelashes and remained steadfast in demanding the paper trail. One would think that, with her level of "expertise", she should have known better.
What this really means is that this project was a vanity project for her, a buddy project for the contractor, and proper controls were deemed "unnecessary" because obviously everything would go fine. Until, of course, it didn't because the controls to prevent that had not been used.
