Here's what it specifically ordered:
* Elimination of all remaining barriers to the free movement of goods, services, capital, and people within the EEC by 1993. This included removing tariffs, quotas, and other restrictions on trade.
* Harmonization of legislation in areas like product standards, technical regulations, and consumer protection to ensure a level playing field for businesses across the EEC.
* Establishment of a framework for the European Commission to propose and implement new laws to achieve the single market goal.
* Strengthening of the European Parliament's role in the legislative process.
* Extension of the European Court of Justice's jurisdiction to cover issues related to the single market.
The Single European Act was a significant step towards deeper integration within the EEC and laid the foundation for the European Union as we know it today.
