- Case of first impression
A case of first impression (known as "primae impressionis" in Latin) is a legal case in which there is no
binding authority on the matter presented. A case of first impression may be a case of first impression in only a particularjurisdiction . In that situation, courts will look to holdings of other jurisdictions forpersuasive authority .Where no persuasive authority exists, a judge will look to legal analogies, legal commentary,
legal brief s of the parties, and his or her own legallogic .In some situations, a case of first impression may exist in a jurisdiction until a reported
appellate court decision is rendered.For example, when
e-mail came to be used in business settings, if some party was sued by another, at some point someone would use the contents of some of the e-mails as evidence in their case. The other side may challenge the use of e-mail in such a case, questioning the validity of the material in question (e-mail, like any electronic document, can be easily fabricated; in fact, absent the use of cryptographic techniques such asdigital signature s, it is far easier to forge e-mail than paper documents). Now, the first court to be asked whether e-mail is valid as evidence would be seeing the question as one of "first impression".
