AS REPORTEDno primary record reached; this is what the reporting says

Is it true that contradictory premises can validate any conclusion?

Partly. While classical logic dictates that contradictory premises validate any conclusion (the principle of explosion), alternative systems like relevance logic and paraconsistent logic reject this principle, making the claim contested depending on the logical framework.
