  4. HAS NOTHING TO DO WITH DOCUMENT BEING TRUTHFUL • EXAMPLE – A FORGED CHECK IS “AUTHENTIC” IF THE PROPONENT (LAWYER OFFERING) CONTENDS IT’S A FORGED CHECK • EXAMPLE – A COUNTERFEIT BILL, OFFERED BY THE GOVERNMENT IN A COUNTERFEITING CASE, IS “AUTHENTIC” IF THE GOVERNMENT CONTENDS IT IS COUNTERFEIT Chap. 13 -- Authentication

  5. PROPONENT CONTROLS HOW MUCH FOUNDATION EVIDENCE IS NEEDED • SHE CAN DECIDE WHAT HER CONTENTION IS: • A STEERING WHEEL FROM A ’99 FORD EXPLORER, vs. • THE STEERING WHEEL FROM P’S ’99 FORD EXPLORER • AN AXE OF THE ZZZ TYPE, vs. • THE MURDER WEAPON Chap. 13 -- Authentication

  6. MUST OF COURSE STAY WITHIN THE BOUNDS OF RELEVANCE • IF “A STEERING WHEEL” HAS NO RELEVANCE, AUTHENTICATION ALONE WON’T ALLOW IT IN Chap. 13 -- Authentication

  14. PROS AND CONS OF AFFID. PRACTICE • PRO: CAN’T BE CROSS-EXAMINED • CON: AFFIDAVITS ARE PREPARED OUT OF COURT AND ARE LOADED WITH HEARSAY STATEMENTS OF THE AFFIANT; NORMALLY INADMISSIBLE • CON: CAN’T BE SHOWN OR READ TO THE JURY Chap. 13 -- Authentication
