Final answer:
The Public Sector Contracts Directive does not apply to all contracts issued by Contracting Authorities due to certain legal exemptions.
Step-by-step explanation:
The Public Sector Contracts Directive does not apply to all contracts awarded by Contracting Authorities. There are certain exceptions defined in legal frameworks where these directives may not be applicable. For instance, specific references to exceptions can be found in documents such as No. 12 Constitutional Revision Article II, Section 8, Article V, Section 13, and Article XII, New Section concerning Lobbying and Abuse of Office by Public Officers. These sections imply that there are constitutional considerations that could exempt certain public contracts from the umbrella of the Public Sector Contracts Directive.
