The ballot box must not be transparent.

The PB shall check the ballot box in the presence of the voter who arrived first at the polling station. The result of this control shall be registered into the control slip which shall be signed by both the members of the PB, and the voter who first arrived at the polling station.

The control slip shall be placed in the ballot box which shall then be sealed in the presence of the first voter, and then this shall be put on Record of the Work of the Polling Board.

Upon the opening of the ballot box, it shall first be checked whether it contains a control slip. If the ballot box does not contain the control slip, the PB shall be dissolved and a new one shall be appointed, and voting at that polling station shall be repeated.

The form of the control slip shall be prescribed by the SEC.
