However, "candidacy" may be the wrong word. If you are confirming her renewed tenure, you aren't merely confirming her candidacy for renewed tenure.
'If the deal is done, and it just needs rubber stamping by the committee, you could wirte, "Confirmation of renewed tenure for Mrs Ivanova."
If, as it appears, that you are voting to accept her nomination as a candidate for renewed tenure (a somewhat complex process!), you could write, "Acceptance of Mrs Ivanova's application for renewed tenure".
