This is an interesting lawsuit...

Court rules Catholic Church is solely responsible for altar wine

Only the Roman Catholic Church is authorized to decide what wine can be labelled sacramental, the Supreme Administrative Court ruled on Tuesday. In a lawsuit filed by a wine-producing company against the Church, the court said that the Church has autonomy to decide which wine may be used in Catholic worship.

Apparently a wine maker was suing the Church for the right to label their wines as sacramental wines.

... the label gives the information that this particular wine is good enough even for the Church and the Church freely chooses to use it at the Holy Mass. It may of course give a signal to other customers as well about the quality of the wine. But the absurd argument of the complainant was that he, as a wine producer, is entitled to such permission by the Church for every wine that has objectively fulfilled the criteria set by the Canonical Law.

The article even uses the word transubstantiation.
