Whenever the people intend to offer at a trial (a) evidence of a\nstatement made by a defendant to a public servant, which statement if\ninvoluntarily made would render the evidence thereof suppressible upon\nmotion pursuant to subdivision three of section 710.20, or (b) testimony\nregarding an observation of the defendant either at the time or place of\nthe commission of the offense or upon some other occasion relevant to\nthe case, to be given by a witness who has previously identified him or\nher or a pictorial, photographic, electronic, filmed or video recorded\nreproduction of him or her as such, they must serve upon the defendant a\nnotice of such intention, specifying the evidence intended to be\noffered.\n 2. Such notice must be served within fifteen days after arraignment\nand before trial, and upon such service the defendant must be accorded\nreasonable opportunity to move before trial, pursuant to subdivision one\nof section 710.40, to suppress the specified evidence.
