Dr Georgia du Plessis
Dr Georgia du Plessis started working on topics related to freedom of expression when in academia, and continued to do so at ADF International, her current employer.

It is on this day that the National Council of Provinces will consider the Prevention and Combating of Hate Crimes and Hate Speech Bill during its plenary session. If the bill is passed, it will become law in South Africa, introducing a very broadly defined crime of hate speech that applies to all South African citizens. 

Dr Georgia du Plessis, Legal Officer at ADF International, Brussels, and Research Fellow at the University of the Free State (UFS) and the University of Antwerp, Belgium, points out that, according to the South African government, one of the objectives of the Prevention and Combating of Hate Crimes and Hate Speech Bill is to fulfil South Africa’s responsibilities as outlined in the Constitution and international human rights instruments.

“Here reference is made to the International Convention on the Elimination of All Forms of Racial Discrimination (to which South Africa is a signatory). However, this convention only refers to issues confined to discrimination based on race, colour, national or ethnic origin and not the extensive list of grounds found in Clause 1 of the bill. Furthermore, the international bill of rights (Universal Declaration of Human Rights, International Covenant on Economic, Social and Cultural Rights and the International Covenant on Civil and Political Rights) places no obligation on member states to implement hate speech laws,” she states.

She strongly believes that “the so-called international obligations requiring such overbroad hate speech laws are not specified and an incorrect understanding of the actual obligations placed upon South Africa by these international instruments”. 

Solving inequalities

Given the deep-rooted inequalities in the country, it is easy to conclude that certain forms of speech contribute to maintaining these historical inequalities, making a case for their regulation and prohibition.

Dr Du Plessis, however, is of the opinion that the current inequalities found in South African society are due to a variety of historical and current factors such as corruption, perpetuated historical inequalities, low employment and education rates, etc., that will not be solved or even alleviated by limiting freedom of expression. “Quite the contrary,” she states. 

She believes there are already measures in place to limit speech that threatens to discriminate and violate the rights of others. Here, for instance, she refers to Section 36 of the Constitution and laws such as the Promotion of Equality and Prevention of Unfair Discrimination (Equality) Act 4 of 2000. “Here Section 10 already prohibits ‘hate speech’ even more broadly than the South African Constitution (Section 16),” she says. 

“The Equality Act is already an overly broad restriction of freedom of speech found in the Constitution,” states Dr Du Plessis. 

According to her, freedom of expression was one of the few tools that can and remains to be used by the vulnerable, oppressed, and poor. “There is no evidence that suggests that such ‘hate speech laws’ will protect the most vulnerable in society and reduce racism. Instead, it gives the government a tool to take away hard-won rights and freedoms that can be used against those very same groups in society that need the most protection. Limiting speech will not reduce inequalities and discrimination. On the contrary, it will disempower those who need it the most,” she says. 

The definition

Dr Du Plessis says, “The current Hate Speech Bill contains a circular definition of ‘hate speech’ which boils down to ‘hate speech’ being defined as ‘hate’.” 

“This lack of narrowly defined concepts, which is necessary for legal certainty in criminal law, can easily be used to the ‘advantage of a government’ and enlist the general public as ‘agents of the control process’,” she states. 

Dr Du Plessis uses blasphemy laws in Nigeria as an example – a country where “blasphemy laws are used as an excuse to act in a discriminatory manner and in violence towards others when the person feels that his or her religion or religious figure has been offended. Deborah Emmanuel Yakubu was stoned and burned to death for posting messages on WhatsApp allegedly insulting and blaspheming against the Prophet Muhammad”.

She suggests that although the Hate Speech Bill may seem different – that it will not allow for such instances within the young democracy – the wording of the current version of the bill is open to being interpreted as putting someone in jail for eight years for causing emotional ‘harm’ (whatever that may mean). “This is not very different from how blasphemy laws operate, which is premised on the emotional subjective experience of the person towards whom the speech is made”.

“In essence,” she says, “Clause 4(1) of the bill states that any person who acts in a manner that can be seen as a clear intention to incite harm and propagate hatred is guilty of hate speech.”

As stated by her, ‘hate’ is not defined further, and ‘harm’ is very broadly defined as any ‘substantial emotional, psychological, physical, social or economic detriment that objectively and severely undermines the human dignity of the targeted individual or group’. Thus, aspects such as ‘offence’ can easily be included under the definition of ‘harm’, even if international law clearly states that speech causing offence cannot necessarily limit the right to freedom of expression as such.

She also points out that there is no universally accepted definition of ‘hate speech.’ “Speech that is defined by an emotion, such as hate, is conducive to the subjective emotional meaning attached to it by the one who utters such speech and the person against whom it is uttered,” she says.

  • Dr Du Plessis lectured public law subjects at the UFS, which included international law, administrative law, statutory interpretation, and human rights law in general. She later received a scholarship to complete her PhD in Law in Belgium on the right to freedom of religion or belief. At KU Leuven in Belgium, she lectured and published on related topics and thereafter started working at ADF International in Brussels. Her work at ADF International involves legal advocacy and research on freedom of religion or belief, freedom of expression, and parental rights – mainly related to the European Union, but also internationally (for example, related matters in South Africa).

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
