Having no equal; one.
Quantitative-Qualitative Friction Ridge Analysis, David R. Ashbaugh 1999 CRC Press

Unique Characteristics
Characteristics used to individualize; specific details.
Quantitative-Qualitative Friction Ridge Analysis, David R. Ashbaugh 1999 CRC Press

Uniqueness
The premise that all fingerprints, friction skin, are unique has been researched to 
the point of general acceptance. Research includes inductive reasoning and includes 
research into how friction skin is formed, i.e., differential growth. General 
acceptance indicates that reasonable doubt for the premise has been eliminated. 
Uniqueness is separate and apart from sufficiency or the strength of a conclusion.

Very uncommon, unusual, atypical, or remarkable; a degree of 
distinguishing distinctiveness.
Quantitative-Qualitative Friction Ridge Analysis, David R. Ashbaugh 1999 CRC Press

United States v. Byron Mitchell (1999)
This was the first legal case where fingerprints evidence was challenged 
at a Daubert hearing.  The defense claimed that the state had failed to 
establish the scientific validity of latent prints stating, "Is there a 
scientific basis for a fingerprint examiner to make an identification, 
of absolute certainty, from a small distorted latent fingerprint fragment".   
The US District Court for the Eastern District of Pennsylvania's decision 
was that the defense's motion to exclude fingerprint evidence was denied.

United States v. Henthorn (1991)
An extension of the Giglio decision which applies to requests for the personnel 
records of government witnesses.

See Brady and Giglio v United States.

United States v. Parks (1991) 
“The only known fingerprint case in which a federal trial court has performed 
the type of analysis that is now mandated by Daubert, the district court 
excluded the government’s fingerprint identification evidence.  United 
States v. Parks (C.D. Cal. 1991) (No. CR-91-358-JSL) (Ex. 48).  The district court 
in Parks reached its determination after hearing from three different 
fingerprint experts produced by the government in an effort to have the 
evidence admitted.  In excluding the evidence, the district court recognized, 
among other things, the lack of testing that has been done in the field, the 
failure of latent fingerprint examiners to employ uniform objective standards, 
and the minimal training that latent fingerprint examiners typically receive.”

The judge decided not to admit the evidence in this case because he had several 
concerns.  The initial examiner, Diana Castro, testified to a point standard (8 points) 
but couldn’t state why that standard was used.  The judge concluded there were 
no written documents or studies to support this standard and therefore the 
conclusion was not scientific.  The supervisor, Darnell Carter, testified that the 
office standard was 10 points but could be reduced with a supervisor’s approval.  
The supervisor could offer no literature to support this policy.  The 3rd expert 
was an IAI Certified Examiner that worked for the United States Postal Inspection 
Service, Steven Kasarsky.  He testified that no studies on errors had been done 
but he knew of cases where 10 points of agree were found in different prints.  
He stated that practitioners all have independent standards and that practitioners 
do not know if a dissimilarity exists in an area that was not left, they must guess.

United States v. Plaza (2002)
Plaza was one of four people being charged as being a hit man.  There were latent 
prints in the case and the defense decided to challenge the fingerprint evidence.  
A Daubert hearing was held.  Federal Judge Louis Pollak ruled that fingerprint 
experts could not tell juries that two fingerprints matched.  It was noted that 
fingerprints were unique and permanent but the science did not meet the Daubert test.  
Judge Pollak reversed his decision two months later.  

Universal Latent Workstation (ULW)
The Universal Latent Workstation (ULW) is software that provides functionality to 
create, edit, and view latent fingerprint transactions. ULW provides operational 
access to FBI IAFIS/NGI latent print services, as well as enabling cross-jurisdictional 
interoperability between vendor-specific AFIS feature formats. ULW also serves as a 
reference implementation to the extended friction ridge feature set, and is often used 
as a multi-purpose tool by fingerprint researchers. ULW was designed, developed, and 
maintained by Noblis (previously known as Mitretek Systems) under contract to the Federal 
Bureau of Investigation starting in 1998; ULW was originally based on concepts by Tom Hopper 
(FBI) and designed by Austin Hicklin (Noblis).
