In cases where there is a violation of the privilege of being represented on the board of directors stipulated in TCC 360, a special committee of privileged shareholders should be convened according to TCC 454. However, in practice, in some cases, it is observed that the TCC 360 privilege is excluded from this scope, even though it is violated. In this direction, in our study, the effects of quorum changes in the articles of association, granting veto right and changing the number of members of the board of directors on the privilege of TCC 360 were evaluated. It is possible for the privilege of being represented on the board of directors to become a stronger privilege by being supported by quorums and thus to increase the effect of the privilege. In such a case, weakening the effect of the privilege by changing the quorum should be evaluated within the scope of the violation in TCC 454 and a conclusion should be reached accordingly. Similarly, we reach the same conclusion in terms of the veto right granted with the TCC 360 privilege, based on the view that the veto right is a link with the privilege. Amending an article of the articles of association related to the concession and claiming that it has nothing to do with the concession leads to unlawful results. Because it is possible to weaken the effect of the privilege of being represented on the board of directors in the stated situation. In our study, the decisions of the Supreme Court on the issues mentioned were examined and evaluated.
