Should the sole partner also be manager, the formalities for convening the general meeting shall not have to be complied with, notwithstanding the obligation to draw up a special report which, as the case may be, shall be published according to the law.

If an external manager has been appointed, the latter shall attend the general meetings, even if he has not been convened to it. The sole partner shall be obliged to invite the manager per registered letter indicating the agenda. This last formality is not mandatory if the manager is prepared to attend the meeting. This consent is mentioned in the minutes of the meeting. In all cases the meeting shall be chaired by the sole partner.
