a. Import and export duties, or charges having equivalent effect, and quantitative restrictions  on the movement of products;

b. Measures or practices which discriminate between producers, between purchasers or  between consumers, especially in prices and delivery terms or transport rates and conditions,  and measures or practices which interfere with the purchaser's free choice of supplier;

c. Subsidies or aids granted by States, or special charges imposed by States, in any form  whatsoever;

Article 5  

The Community shall carry out its task in accordance with this Treaty, with a limited measure  of intervention.

To this end the Community shall:

• Provide guidance and assistance for the parties concerned, by obtaining information,  organizing consultations and laying down general objectives;
• Place financial resources at the disposal of undertakings for their investment and bear  part of the cost of re-adaptation;
• Ensure the establishment, maintenance and observance of normal competitive  conditions and exert direct influence upon production or upon the market only when  circumstances so require;  
• Publish the reasons for its actions and take the necessary measures to ensure the  observance of the rules laid down in this Treaty.

The institutions of the Community shall carry out these activities with a minimum of  administrative machinery and in close cooperation with the parties concerned.

Article 6

The Community shall have legal personality.

In international relations, the Community shall enjoy the legal capacity it requires to perform  its functions and attain its objectives.

In each of the Member States, the Community shall enjoy the most extensive legal capacity  accorded to legal persons constituted in that State; it may, in particular, acquire or dispose of  movable and immovable property and may be a party to legal proceedings.

The Community shall be represented by its institutions, each within the limits of its powers.
