Irish Prime Minister Leo Varadkar said he did not want to "comment on court cases that are happening in the UK. They'll play themselves out".
He told a press conference in Denmark the EU would consider a request for a further Brexit extension if Mr Johnson asked for one, adding: "Certainly an extension would be better than a no deal".
However, he said many other EU countries would need a "good reason" to approve a further delay to the UK's exit.
He said his preference was to reach a deal with the UK by the summit of European leaders on 17 October and said he believed this was still possible.
"Our focus is getting a deal at the EU Council and I believe that's possible," he added.
Here the renowned fellow Varadkar, high official of the Irish government itself, proposes a last possible exit to diplomacy debouching at the October 17 EU Council Meeting.
It's a gracious gesture, but also cautionary if many nations truly need convincing for further extensions. Any extension requires unanimous consent.
The longer the EU lets Brexit drag on, the more expensive the eventual booting of Britain becomes for the economies of the EU's member states, it says here.
Anyhow, I would say Taoiseach rather that Prime Minister, which is more of a Boris Johnson thing.
