Williams v Natural Life Health Foods
A rather good example as this was a single person company, yet the court found that that only the company was liable for negligence as the duty of care to the client rested with the company alone and not the individual, even though that individual had provided the advice that lead to the claim.
This case is not an example of what you wrote, which is "Situations where there may be a systemic failure that cannot be attributed to any single individual. So in a court you would never reach the threshold for individual liability but may easily reach the threshold for corporate liability."
The failure in this case could be attributed to an individual - the sole director of a company. He was acting on behalf of the company (the principal). He had been heavily involved in the services the company provided. However, while the failure could be attributed to him and he is morally liable, the House of Lords held he is not legally and therefore economically liable for his failure to the tune of £85,000 based on the principle that "reliance upon [the assumption of responsibility] by the other party will be necessary to establish a cause of action.... It is not sufficient that there should have been a special relationship with the principal [the company]. There must have been an assumption of responsibility such as to create a special relationship with the director or employee himself. It's an objective test.
"An objective test means that the primary focus must be on things said or done by the defendant or on his behalf in dealings with the plaintiff. The enquiry must be whether the director, or anybody on his behalf, conveyed directly or indirectly to the prospective franchisees that the director assumed personal responsibility towards the prospective franchisees".
The concept of a company being a separate legal entity from those who own and manage it initially came about in order to partition the assets owned by a company from the assets owned by shareholders or members of the company e.g. the shareholders might own assets in a different unincorporated business but the assets of that unincorporated business would not be mixed with the assets of the company. This separate legal entity concept allowed the company to govern the use of assets it was deemed to own. It was later developed such that a trader who incorporates a company to which he transfers his business creates a legal person on whose behalf he may afterwards act as director. The Law Lords in this case said that "For present purposes, his position is the same as if he had sold his business to another individual and agreed to act on his behalf. Thus the issue in this case is not peculiar to companies. Whether the principal is a company or a natural person, someone acting on his behalf may incur personal liability in tort as well as imposing vicarious or attributed liability upon his principal."
The veil of incorporation is a legal not a moral concept. It protects individuals who want to go into business by limiting their personal liability as shareholders or directors or employees e.g. if there is a cock up by an individual in the company. This is one of the reasons why people in business incorporate rather than act as sole traders or partners.
You still have not explained what any of this has to do with the idea that religions as opposed to individual people can act to supress ideas being explored. The issue being discussed was not about legal liability. A religion is not a company and a religion does not make decisions and a religion is not a separate entity - individual people make decisions about whether they will supress other people's ideas that they interpret as being contrary to their understanding of their religious scripture or their political ideology. Individuals are not required to act this way - they take it upon themselves to do so. In the same way that Twitter mobs or Sussex police officers take it upon themselves to act against people whose opinions they disagree with. You have not responded to this point in my posts about whether individuals are morally responsible, despite me bringing it up several times.
