When it comes to public tenders there should be automatic clawbacks and penalties factored in to prohibit this sort of nonsense in the first place. No real bidding process? Fine the company, fire the bureaucrat who got bought off. Abusing taxpayers like this should automatically result the company paying back the difference of what it would have actually cost.
