The public sector contract law is based on the principles of free competition and equal opportunities. Any company, entity, or person from all over Catalonia can submit bids for public administration tenders. This also applies to those from the Spanish State and any country in the European Union. The awarding bodies are very demanding and do not accept any criteria that discriminate on the grounds of origin or nationality. However, these public tenders, which are necessary to guarantee transparency and prevent favoritism, sometimes result in surprising awards, with decisions that are difficult for citizens and local businesses to understand.
