Analysts have suggested that the litigation might be a case of spurned advances, speculating that J-Date launched the legal action after an acquisition offer was turned down.

Meanwhile a rabbi has waded in to the unfolding drama, by saying that the lawsuit would be frowned upon by Jewish law.

“From a Judaic ethics standpoint, it’s inappropriate,” said Rabbi Shlomo Yaffe, Dean of the Institute of Talmudic Law. “We’re talking about creating Jewish families with Jewish children. We should encourage competition.”
