Property developers countering govt policy
In the late 1970s, never mind making it illegal for property developers to absorb any stamp duty: someone would call up the developers offering this deal and tell them that what they were doing was “not in the national interest”, and please scrap the offers. Developers would listen to the polite request to behave responsibly in obeying the spirit of the law rather than the letter of the law because no developer wanted the tax authorities going thru their books if they decided to follow the letter of the law.
How times have changed since when I started work. For the better or the worse in this instance, I am uncertain.
