CHAP. 13: AUTHENTICATION P. JANICKE 2014

AUTHENTICATION • A SUBSET OF RELEVANCE • AUTHENTICATION EVIDENCE IS – NEEDED BEFORE DOCUMENTS AND TANGIBLE THINGS ARE RECEIVED IN EVIDENCE – NOT NEEDED FOR TESTIMONY 2014 Chap. 13 -- Authentication 2

MEANING OF AUTHENTICATION PROOF: • EVIDENCE THAT THE DOCUMENT (OR PHYSICAL THING) IS WHAT ITS PROPONENT CONTENDS IT IS – EXAMPLE: THE STEERING WHEEL FROM THE DEFENDANT’S CAR – EXAMPLE: A CHECK WRITTEN AND SIGNED BY D. 2014 Chap. 13 -- Authentication 3

• 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 2014 Chap. 13 -- Authentication 4

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 2014 Chap. 13 -- Authentication 5

STILL NEED RELEVANCE • MUST OF COURSE STAY WITHIN THE BOUNDS OF RELEVANCE • IF “A STEERING WHEEL” HAS NO RELEVANCE, AUTHENTICATION ALONE WON’T ALLOW IT IN 2014 Chap. 13 -- Authentication 6

CHAIN OF CUSTODY • ONE METHOD OF AUTHENTICATING ITEMS THAT COULD HAVE BEEN ALTERED • NO HARD-AND-FAST REQUIREMENTS • CHAIN WITH BROKEN LINKS SOMETIMES RULED O. K. 2014 Chap. 13 -- Authentication 7

TAKING THE AUTHENTICATING WITNESS ON VOIR DIRE • TEXAS : “VORR DYER” • REST OF U. S. : “VWAHR DEER” • COURT PERMISSION NEEDED PER RULE 611 – BUT PERMISSION IS OFTEN ASSUMED 2014 Chap. 13 -- Authentication 8

• IT IS GENERALLY IMPROPER TO TAKE THE AUTHENTICATING WITNESS ON VOIR DIRE PRIOR TO TIME WHEN THE DOCUMENT OR OBJECT IS OFFERED IN EVIDENCE – WOULD UNDULY INTERRUPT THE FOUNDATION EVIDENCE OF THE PROPONENT – BUT UPON THE OFFER, VOIR DIRE IS NORMAL 2014 Chap. 13 -- Authentication 9

PURPOSES OF VOIR DIRE • TO DEFEAT THE FOUNDATION AND KEEP THE ITEM OUT OF EVIDENCE • IF THE ITEM COMES IN, TO WEAKEN ITS IMPACT 2014 Chap. 13 -- Authentication 10

AUTHENTICATION • JUDGE IS GATEKEEPER, AS USUAL • JUDGE’S RULING IS NOT BINDING ON THE JURY • JUDGE IS NOT BOUND BY EVIDENCE RULES (EXCEPT PRIVILEGE) 2014 Chap. 13 -- Authentication 11

JURY IS THE ULTIMATE DECIDER OF ALL FACTS (INCLUDING AUTHENTICITY) • THEREFORE, MOST LAWYERS CHOOSE AN AUTHENTICATION METHOD THAT FOLLOWS THE RULES OF EVIDENCE AND CAN BE INTRODUCED IN JURY’S PRESENCE 2014 Chap. 13 -- Authentication 12

WAYS TO AUTHENTICATE [RULE 901(b)] • TEN ARE LISTED IN THE RULE • LIST IS ILLUSTRATIVE, NOT EXCLUSIVE 2014 Chap. 13 -- Authentication 13

AFFIDAVIT TESTIMONY ON AUTHENTICITY – OFTEN USED IN BENCH TRIALS – IN JURY TRIALS, AFFIDAVITS ARE USUALLY INADMISSIBLE HEARSAY 2014 Chap. 13 -- Authentication 15

METHOD #3: COMPARISON BY EXPERT WITNESS OR BY JURY – COMPARISON TO PREVIOUSLY ADMITTED SPECIMENS – WITH JURY, THERE’S NO WAY FOR THEM TO PRE-ANNOUNCE THEIR RULING ON AUTHENTICITY (LEFT IN THE AIR) 2014 Chap. 13 -- Authentication 17

METHOD #4: DISTINCTIVE CHARACTERISTICS – PROBLEM: POINTING THEM OUT WITHOUT A WITNESS – WORKABLE ONLY IN BENCH TRIALS 2014 Chap. 13 -- Authentication 18

VOICE AUTHENTICATION METHOD #5 • REQUIRES FAMILIARITY • BUT IT CAN BE ACQUIRED AFTER A PHONE CALL IN QUESTION • E. G. , BY HEARING A PARTY SPEAK IN COURTROOM OR IN A DEPOSITION 2014 Chap. 13 -- Authentication 19

• SO FAR, WE KNOW 2 TYPES OF DOCUMENTS THAT ARE NOT HEARSAY – DOCUMENTS WRITTEN BY THE OTHER SIDE – DOCUMENTS THAT CONSTITUTE AN ELEMENT OF THE CASE (E.
