What is the effect of the certification by the drawee bank?

Certification implies that the check is drawn upon sufficient funds in the hand of the drawee, that they have been set apart for its satisfaction and that they shall be so applied whenever the check is presented for payment. Where a check is certified by the bank on which it is drawn, the certification is equivalent to acceptance (New Pacific Timber v. Seneris, G.R. No. L-41764, Dec. 19, 1980).
