Judgments, orders or decrees other than those mentioned in section 41, are relevant if they relate to matters of a public nature relevant to the enquiry, but such judgments, orders or decrees are not conclusive proof of that which they state.

Illustrations
A sues B for trespass on his land. B alleges the existence of a public right of way over the land, which A denies.
The existence of a decree in favour of the defendant, in a suit by A against C for a trespass on the same land in which C alleged the existence of the same right of way, is relevant, but it is not conclusive proof that the right of way exists.
