Is the authentic Mursal Hadith legally acceptable and reliable, bearing in mind that the term "authentic Mursal" is unknown?

A Mursal Hadith (definition) is one that a Tabi'i (successor to a Companion) raises directly to the Prophet, peace and blessings be upon him, or one from whose chain of narration a narrator is missing. Scholars have differed regarding its admissibility as evidence. Some have accepted it, while others stipulated for its acceptance that it must be from the senior Tabi'in. The majority of scholars do not use it as evidence due to ignorance of the missing narrator. The term "Mursal Sahih (definition)" (authentic Mursal) means that the chain of narration is authentic up to the Tabi'i who transmitted it as Mursal.
