Update 1:
This question pertains specifically to law in the United States of America, more specifically criminal law. However, I reason it may be applicable to the law of other lands.
Update 2:
The relevant part of proceedings of which I am imagining the motion to acquit would be made would be after the jury has rendered its verdict of guilty or not guilty in relation to whether or not a defendant is guilty or not guilty (more specifically, in a post-trial motion to the trial court judge, relative to ohwilleke's comment, if I grasp things correctly).
Update 3
Many of the arguments failed to touch upon my initial question, which has been "Does due process require that the grounds for a conviction can be substantiated?"
It appears to me through analysis that the answer to my question is "Yes." This has further come to my attention through realizing from ohwilleke's comment that a motion to acquit may involve making such motion on the basis that there is insufficient evidence to convict a defendant, whereby the expression "insufficient evidence to convict a defendant" is synonymous with the expression "the grounds used to convict the defendant could not be known as sound." If there is insufficient evidence to convict a defendant, then such conviction would be a due process violation.
Relative to Rene Descartes' evil genius argument in his meditations the following is argued as a basis to declare that there is never sufficient evidence to support a conviction: No rational trier of fact can know without the possibility of error whether or not any information encountered by such rational trier of fact is representative of actual evidence of a defendant’s guilt in order for such rational trier of fact to take such information into consideration as representative of actual evidence in order for such rational trier of fact to determine whether or not such defendant is guilty beyond a reasonable doubt of having committed a crime based on any such information in order for such rational trier of fact to convict such defendant of having committed a crime based on any such information.
That leaves the question remaining, "How does a person know if she or she knows something," for which I presume the answer is that the person has knowingly satisfied the criteria for such: No rational trier of fact can knowingly satisfy the one or more necessary or sufficient criteria are required to be satisfied in order to know without the possibility of error whether or not any information encountered by such rational trier of fact is representative of actual evidence of a defendant’s guilt.
People have made answers that have not targeted my initial question. Furthermore, the closure of the thread was fallacious.
Regardless, this question has been answered.
--- Original post is as follows:
I have been working on drafting legal and legal-like motions, but I have been failing to figure out how to argue whether or not a certain motion should be granted. To keep in line with this post being educational, I will focus on the motion of "motion to acquit," as I am not currently seeking legal advice for it and it will provide and basis for discussion.
So, from what I have studied from philosophy, there is Descartes's evil genius / evil demon argument that posits that we cannot be sure of anything about our reality. Relative to law, that means that a person cannot be sure that the alleged or presumed evidence that is being used to sustain a conviction is representative of actual evidence. It could be that an evil genius has deceived persons as to what the actual facts of the case are, thus crippling persons from having awareness of what alleged or presumed evidence is representative of actual evidence.
For sake of argument, it is presumed that in order to ensure that one is not being deceived by as to what the actual evidence of a case is, then such persons needs to have authority in order to ensure such, whereby it is presumed such authority can only be obtained by the person partaking of absolute control of reality, which would allow the person to account for whether or not he or she is being deceived.
Thus, I am thinking that it may be allowed as the necessary criterion for a motion to acquit to be made that it is not possible for anyone to know whether or not the grounds for the conviction are sound or not sound, whereby it is presumed that due process requires such can be known in order to prevent a false or speculative conviction in order to prevent a miscarriage of justice.
The reason it is not possible for anyone to know whether or not the grounds for the conviction are sound is because no one has the authority in order to know such.
However, I think the soundness of such motion is dependent on whether or not due process allows for its grounds to be considered sound.
