"In 1923 Mrs. Mardon was carrying on the business of an
ironmonger at Devonia. No doubt the covenant was taken
for the benefit of that business and to prevent competition
therewith, but I see no reason to think, and there is nothing
in the conveyance of 1923 which leads me to believe, that
that was the sole object of taking the covenant. Mrs. Mardon
may well have had it in mind that she might want ultimately
to sell her land and the business and the benefit of the covenant
in such manner as to annex the benefit of the covenant
to Devonia for, by so doing, she would get an enhanced
price for the totality of the assets which she was selling;
a purchaser would surely pay more for a property which
would enable him to sue in equity assigns of the defendants'
premises taking with notice and to pass on that right, if he
so desired, to his successors, than for a property which would
only enable him to sue the original covenantor, for that is the
result of the view urged on me by Mr. Bowles.
Further, Mrs. Mardon may well have thought that her own
business might ultimately be closed down, or the goodwill
thereof sold to someone who was going to carry it on on
some other premises. She would then be left with Devonia,
and Devonia could be sold at an enhanced price to someone
intending to carry on the business of an ironmonger, because,
if, as part of the sale transaction, he obtained the benefit of
the covenant, he could prevent competition from the defendants'
premises opposite in the trade.
In my judgment, it was always open to Mrs. Mardon, when
she desired to dispose either of the land or the business, to
assign the benefit of the covenant with the one or the other
or both as she chose. By taking this covenant, she was thereby
enabled to sell her premises, or her business, to better
advantage as she thought fit. In my judgment, Mrs. Mardon
was in the position of the vendor in the example given by
Cozens-Hardy M.R. in Reid v. Bickerstaff (1909) 2 Ch 305, at p 320 , where
