Yesterday's South China Morning Post carried a full page petition signed by 1,768 journalists protesting against the Hong Kong government's plans to restrict public access to information about company directors.
I signed the petition not so much because the government's proposal is a blatant attempt to limit press freedom - although it is that. I signed because in trying to conceal crucial details like the identity card numbers of company directors, the government is guilty of a gross betrayal of its public duty.
To see why that is, and to understand why the government's explanation that it merely wants to "enhance protection of the privacy of personal information" is utter hogwash, we need to remind ourselves just what companies are and why they exist.
If you or I take out a mortgage to buy a flat and find ourselves unable to make the monthly payments, the bank that granted us the mortgage will come after us for its money.
It would start by repossessing our flat. But that's not all. If prices had slumped since our purchase, we might be unlucky enough to be in negative equity, with the value of our mortgage exceeding the current market value of the property. (Incidentally, if Hong Kong property prices fall by half from their present level, negative equity is exactly where tens of thousands of homeowners will find themselves.)
In that case the bank, or more likely its thuggish debt collector, would seize anything else of ours it could get its hands on - bank deposits, shares, car, jewellery and so on - until our debt and its costs were paid in full.
But if you and I were to set up a company to buy our flat, the story would be different. Most of the one million companies registered in Hong Kong are established as limited liability concerns. As a result, the bank would be allowed under law to seize only assets directly owned by our company. Everything else we own would be safe from its predations.
In short, the shareholders and directors of limited companies (and for most small private companies they are either the same people or the directors are close affiliates of the owners) enjoy privileged public protection should their companies run into trouble.
This protection is so important that when historians scratch their heads over why the industrial revolution and the explosion of wealth it produced took place in the relative backwater of western Europe rather than somewhere else with more obvious advantages, like China, they often conclude that the deciding factor was the development in Europe of limited liability.
With the assurance that their potential losses would be restricted to no more than the money they originally staked, investors proved far more willing to risk their capital in new business ventures. Today, limited liability is regarded as one of the cornerstones of a functioning economy.
But limited liability cannot be granted unconditionally. In return for the privileged public protection they enjoy, companies must divulge unique details about the identities of the directors they appoint. In Hong Kong that means either a local identity card number or a passport number.
This disclosure is crucial. Without unique identifiers, banks cannot do credit checks, business counterparties cannot conduct essential due diligence and - yes - journalists cannot expose fraud and corruption.
The disclosure of company directors' ID card or passport numbers is in the vital public interest. And it is nothing more than the necessary corollary of the privileged public protection limited liability companies enjoy.
In seeking to declare company directors' details secret, the government is directly attacking not only Hong Kong's public interest but also the foundations of its economy.
I can only conclude that our officials have something really big they want to hide from us.
