Representing Cheshire East Council, Christopher Katkowski told the inquiry that the protection of Jodrell Bank was "a matter of global significance", because the Lovell Telescope's work is "internationally important".
The inspector, Gareth Jones, admitted that he was "no expert" in radio astronomy, but he may be making a visit to the observatory to understand its work as part of the process.

Gladman Developments launched an appeal after the council refused its application, claiming there was "no evidence" their plans would cause a significant increase in radio interference.Gladman Developments launched an appeal after the council refused its application, claiming there was "no evidence" their plans would cause a significant increase in radio interference.
In a statement to Cheshire East Council, the company said it is "prepared to work with (Jodrell Bank) and consider any reasonable mitigation measures that they might suggest to alleviate their concerns." The firm argues that the village of Goostrey already produces radio interference, so 119 extra homes would not make an unacceptable difference.
Richard Kimblin QC added that the situation may have "some apparent complexities" but insisted the developer's case was quite simple: not enough homes are being built in the east of Cheshire.
