Dear Experts, 

I would be grateful if you could share your opinion on the following question:

Article 16 c(iii) b says: - When a nominated bank acting on its nomination, a confirming bank, if any, or the issuing bank decides to refuse to honour or negotiate, it must give a single notice to that effect to the presenter . .  The notice must state:

iii) . . . b) that the issuing bank is holding the documents until it receives a waiver from the applicant and agrees to accept it, or receives further instructions from the presenter prior to agreeing to accept a waiver; 

and article 16(e) says

A nominated bank acting on its nomination, a confirming bank, if any, or the issuing bank may, after providing notice required by sub-article 16 (c) (iii) (a) or (b), return the documents to the presenter at any time. 

The question is as follows: If its notice of refusal issuing bank states the following wording "We are holding the docs until we receive a waiver from the applicant and agree to accept it" does it mean that after receiving of waiver the issuing bank cannot return the documents as per article 16e?  Don these 2 articles contradict each other?

Alternatively can the bank state only "We are holding the docs until we receive a waiver from the applicant" without stipulating "agree to accept it",  and in this case is the bank acting in accordance with UCP 600?

Many thanks in advance
