6.Where the simple cooperation procedure under Article 6 of this Regulation is applied, the lead supervisory authority shall submit a draft decision pursuant to Article 60(3) of Regulation (EU) 2016/679 within 12 months of the lead supervisory authority confirming its competence pursuant to Article 4(6) of this Regulation or of a binding decision by the Board pursuant to Article 65(1), point (b), of Regulation (EU) 2016/679.Where national law requires prior or subsequent domestic proceedings which necessitate that a draft decision pursuant to Article 60(3) of Regulation (EU) 2016/679 be submitted after the expiry of the time limit referred to in the first subparagraph, the lead supervisory authority may extend that time limit once, for a period of no longer than two months. In such a case, the lead supervisory authority shall inform the other supervisory authorities concerned of the extension of the time limit, setting out the duration of that extension, at least two weeks before the expiry of the time limit referred to in the first subparagraph.
