Nolo contendere
Residual effects

Under the Federal Rules of Evidence, and in those states whose rules of evidence are similar or identical to them, nolo contendere pleas may not be used to defeat the hearsay prohibition if offered as an "admission by party-opponent". Assuming the appropriate gravity of the charge, and all other things being equal, a guilty plea to the same charge would cause the reverse effect: An opponent at trial could introduce the plea, over a hearsay objection, as evidence to establish a certain fact.
