This prohibition shall apply in all cases, disputes, or controversies instituted by a party, including, but not limited to, cases filed by bidders or those claiming to have rights through such bidders involving such contract. This prohibition shall not apply when the matter is of extreme urgency involving a constitution issue, grave injustice and irreparable injury will arise. The applicant shall file a bond, in an amount to be fixed by the court, which shall accrue in favor of the government should the court finally decide that the applicant was not entitled to the relief sought.
