What does it mean to say one has a right to something, such as access to housing or to protest or to property? What are human rights? What do they ‘do’?

One often hears of human rights being asserted as if they give one an absolute claim to something specific and discrete, which can be enforced against anything and everyone else, irrespective of the impact on the interests (and rights) of others, as well as broader public goals or values.

Perhaps the clearest example of this was the way in which the right to ownership of land was understood under apartheid property law. Ownership then was an absolutely exclusive right: it entitled its holders to exclude everyone else without a countervailing right from their land, irrespective of circumstance or context. All a landowner had to prove before a court to obtain an eviction order if they sought to evict someone from their land, was that they had the right (owned the land) and that those they sought to evict had no countervailing right in law to be on the land. If the right was proved in this way, the remedy of exclusion through eviction followed automatically – the court had to grant the eviction order.

Constitutional right to peaceful protest

A more recent example of this view was on display in the way in which members of parliament complained about their removal from the house when they attempted to shut down the President’s State of the Nation Address through protest action. Many responded by saying their removal was unjustified because, by trying to stop the address from proceeding, they were exercising their constitutional right to peaceful protest. The assumption underlying this response is that the right to protest peacefully and unarmed entitles you to protest peacefully and unarmed in any way you see fit and regardless of the consequences for other people and for society at large.

With this view of rights, a right bestows on its holders a sphere of absolute inviolability – an abstract space within which they can do what the right entitles them to do (protest, hold property, speak, associate or whatever), subject to nothing and no-one else, with no limitations. Rights are seen as instruments through which to separate ourselves from other people and unilaterally impose our will and our interests on others. Rights operate as trumps, boundaries, conversation stoppers.

Understanding human rights

Fortunately, our constitution embodies a different vision or understanding of human rights. In various ways, our constitution makes it clear that what exactly our human rights entitle us to do, or have, or experience, is never abstractly fixed, immutable, or absolute, but must always be determined anew within context. Whenever we seek to exercise one of our human rights, its precise contours and limits must be determined in light of the circumstances prevailing at the time we seek to exercise it; the history of our country; the impact that our exercise thereof will have on the rights and interests of other people; and how our conduct in terms of the right aligns with the public interest and broader constitutional goals.

In this view of rights, our understanding of the right of ownership (which is of course not one of the human rights proclaimed in our constitution but is only indirectly protected in Section 25 of the Constitution) has been moulded into something entirely different from the apartheid conception. Landowners no longer have absolute, exclusive control over their land that simply arises from the fact that they have the right to ownership. If landowners today want to remove people occupying their land without any legal right to do so – in addition to and after proving their ownership – they must persuade a court that eviction would be just and equitable in light of all relevant circumstances (prevailing circumstances; interests of others, including the occupiers of their land; the public interest; constitutional goals) before they will succeed.

WATCH: The Power of Human Rights 




Building democracy

Likewise, if we seek to exercise our right to protest – in order to know what we would be entitled to do in terms of that right – we must consider how our protest will affect the rights and interests of others and whether that impact can be justified, and how the manner and form of our protest squares with constitutional goals such as building democracy. Equally, of course, if others object to our protest because of its impact on their rights and interest, they will have to contextualise their attempt to exercise their right to education, or academic freedom, or freedom of movement in light of our interests, the prevailing circumstances, the public interest, and constitutional goals such as fostering democracy, freedom of association, and freedom of speech.

That is, instead of rights in our constitutional order being abstract spheres of inviolability that can be exercised against others to protect or enforce our interests without consideration of context, keeping us apart, they are mechanisms to enable us to live together, to find accommodation between our disparate, perhaps conflicting, but often overlapping interests and concerns.

What is it then that our human rights do for us or entitle us to? Whenever our human rights-related interests are at stake, or if we rub up our fellow human beings with whom we cohabit the wrong way when our interests seem to clash, they entitle us to be taken equal account of. They require others (most importantly those in authority, usually the state) to include us and have concern for our interest, equal to the concern for others, in the conversation about what should happen and what we may or may not do. In this sense, rights do not keep us apart or stop conversations. Instead, they are acutely democratic mechanisms, making it possible for us to live together. ‘Only that?’, you may respond – but this is no small thing.

A summary of an inaugural lecture delivered by Prof Robert Bragg at the University of the Free State:

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
