The Rebbe's Response Concerning an Eruv in Doncaster, Circa 5745
When Rabbi Mordechai Zev Gutnick asked whether he should become involved in an eruv question in Doncaster, the Rebbe's response emphasized the difficulty of the subject and questioned why he should enter it.
A local question in Doncaster
Rabbi Mordechai Zev Gutnick was asked to become involved in an eruv question in Doncaster, a suburb of Melbourne. He brought the matter to the Rebbe rather than treating his general rabbinic experience as sufficient to enter a difficult local dispute.
The question was about his own involvement. It did not present a full survey of the proposed route or ask for a general ruling on every eruv in Australia.
Why enter such a complicated matter?
The response refers to the well-known complexity of hilchos eruvin and asks why Rabbi Gutnick should enter the matter. Its tone is cautionary: a Rav should not assume responsibility for a difficult public eruv without the necessary reason, expertise, and command of the local facts.
That direction fits the Rebbe's other correspondence. City eruv questions were to be handled by qualified local Rabbonim after serious investigation, with close attention to the public consequences.
The wording preserved by Rabbi Binyomin Klein
Rabbi Binyomin Klein transmitted the response, and it was later printed in a teshura. The complete published page is reproduced here so the short answer can be read with its identification and surrounding material.
Doncaster supplies another example of the Rebbe's caution in a particular city. Crown Heights has its own direct testimony and its own Beis Din ruling.
