You seem to not get the fundamental distinction in sacramental theology between an ILLICIT consecration of the species and an INVALID consecration of the Eucharistic species.
Here is the proof of your ignorance. You say,
"You are in fact denying the existence of invalidating laws which are by definition laws that prohibit an act that is always invalid by the nature of the act itself or the actor. This example was previously given: The Church has moral prohibitions against a layman impersonating a priest and hearing confessions. In such a case there is no sacramental absolution taking place."
But, Drew, Canon 817 does not say that the act of consecrating one species without the other is "invalid." It says it is "nefas," not invalid by the act itself. You are just making up your own Canon and sacramental theology.
The example you then give proves your ignorance even further. You suggest that the consecration of one species without the other would be identical to "a layman impersonating a priest and hearing confessions."
No, Drew the two acts are completely different. A real priest could validly but illicitly consecrate one species without the other because he is a real priest. The layman could not validly consecrate any species of the Eucharist because he does not have the power of priestly Holy Orders. We don't even need to get into whether it is licit or illicit for a layman to attempt the Eucharistic consecration. The layman even attempting that is a dud from the get go. The layman is shooting blanks.
But the real priest absolutely can, sacrilegiously and illicitly, consecrate one species without the other, under certain circuмstances. He should never do it. We agree on that. That is why Canon 817 is included in Canon Law to try to make sure that it doesn't happen.
Some of the situations in which a priest could validly, but illicitly consecrate one species without the other are. Here is what I provided for you to read earlier:
The Commentary on the 1917 Code gives a few scenarios: 1) consecrating one species without the other inside the Mass (valid); 2) Consecrating only one species only, presumably outside of Mass, for Viaticuм (valid); 3) consecrating outside of the Mass, presumably for some sacrilegous reason (probably invalid).

Angelus,
Your are referencing a commentary on canon law to overturn Catholic Dogma. It is dogma, that is, a formal object of divine and Catholic faith that the
matter for the sacrament of the Holy Eucharist is bread AND wine. This dogma is affirmed by both the Council of Florence and the Council of Trent. You like the SSPX do not believe that dogma has to be taken literally. The definition of a heretic is a Catholic who rejects dogma.
From dogma, other necessary truths can be deduced with certainty. The canon in question forbids the consecration of a single species. This is an invalidating law because Catholic dogma affirms the truth that
bread AND wine are the necessary matter of the sacrament. The other canonical prohibition of forbidding consecration outside of the holy sacrifice of the Mass is also invalidating law because, firstly, it is in the same canon with a known invalidating law, and secondly, the law permits no exceptions whatsoever. No law, order, command, injunction, proscription, etc., etc. binds in cases of necessity or impossibility. The maxim is 'Necessity known no law' and this truth is affirmed in canon law and Catholic moral theology. The only exception to this maxim is invalidating laws and this can be known by the fact the the law permits
no exceptions whatsoever.
What you have proposed is a corruption of law and a corruption of divinely revealed Catholic truth. What you propose is a lie. It is just as serious a lie to corrupt the hierarchical order of truth as to deny a specific truth. You have a gross disordered sense of proportion when you appeal to a human opinion to overturn God's truth.
The SSPX has denied all the Catholic dogmas the pertain to what is necessary for salvation as a necessity of means. They believe that any "good-willed" pagan, Hindu, Jew, Moslem, heretic, or schismatic can be saved by virtue of his belief in a 'god who rewards and punishes' without the belief in any divinely revealed truth, without the reception of any sacrament, without being a subject of the Roman pontiff, and without membership in the Catholic Church. This denial of the literal meaning of Catholic dogma is again seen in their defense of Bakery and Wine Cellar consecrations where they have corrupted Catholic dogmas on the sacraments, driven a wedge between the sacrifice of the Mass the the Sacrament, and corrupted the nature of the priesthood itself from a participation in the divine priesthood of Jesus Christ to sorcerer.
This is what you believe, what you have defended and what you deserve.
Drew
P.S. In your previous post, you attributed to me something I never said. In this post you have not corrected or apologized for your lie. It matters not to me but others should know who you are.
