Not Simply Teaching Law, But Cultivating Justice and Community: Reflections on Margaret Castles’ Legacy

By Peta Spyrou and Matthew Atkinson

The authors thank the many colleagues, practitioners, former students and friends who contributed reflections and photos about Margaret Castles for this piece.

For over three decades, Margaret Castles, or simply ‘Marg’ as she is affectionately known, has helped shape how dispute resolution is practised, taught, and understood in South Australia and beyond.

Anyone who knows Marg also knows she is deeply uncomfortable with too much fuss being made about her, let alone her recent retirement. Even so, bringing together reflections from former students, colleagues, practitioners, and friends for this piece makes it clear just how profound her contribution to dispute resolution, clinical legal education, and access to justice has been. What began as an effort to mark a retirement instead became a collective reflection on the influence she has had on the people and communities around her.

Marg joined the Adelaide Law School in the mid-1990s to establish what was then a relatively novel idea for the institution: clinical legal education. What began as a small, resource-constrained program has, over time, become a cornerstone of legal education and access to justice in South Australia. From early externships and a modest Magistrates Court advice service, the program expanded into a network of clinics, partnerships, and outreach initiatives that continue to serve communities and improve access to justice across the state.

But to describe Marg’s contribution solely in institutional terms risks missing what has mattered most. Whether supervising PhDs, teaching in the classroom or the clinic, taking students on educational trips, mentoring, or working alongside colleagues, Marg taught and supported others with intellectual rigour, practical wisdom, and deep humanity. With her, students learned not only how to practise law, but what it means to be a lawyer.

Across the reflections gathered for this piece, one theme recurred: Marg’s belief that students learn through doing the work itself—with care, reflection, and responsibility.

Reflecting on her first year of teaching, Dr Kellie Toole recalled finding herself overwhelmed trying to explain complex procedural doctrines to students:

I tangled up the first seminar on Anshun estoppel, Res Judicata and issue estoppel and threw myself at Marg’s mercy to explain them to me between classes. Instead she said ‘oh they are tricky, shall I come in?’ … Marg somehow made me feel supported not mortified. I and both seminars [students] learned about law and everyone’s dignity was intact: that is Marg’s gift.

Dr Rachel Spencer reflected on Marg’s lasting influence as both an educator and colleague.

Recalling their first meeting in 1999, Rachel writes:

Marg and I clicked from the moment we met in 1999 and she invited me to collaborate in Adelaide’s first clinical legal education program based in a tiny room upstairs at the Adelaide Magistrates’ Court. The classes that we co-taught with combined Adelaide and Flinders students were the most memorable and most enjoyable of my academic career.

Rachel also described Marg as a role model for authenticity and a trusted sounding board on access to justice issues:

Watching Marg interact with students taught me to relax as an educator and to be myself. Congratulations Marg on an outstanding career where your care for students, colleagues and clients has been not only exemplary but so very much appreciated.

For Dr Ross Savvas, Marg has been a teacher, mentor, colleague and friend for more than 20 years. Ross’s connection with Marg began when he was a student in the joint university clinic at the Adelaide Magistrates Court and continued throughout his professional life. As Ross reflects: ‘My commitment to pro bono continued in my private practice with a foundation based on Marg’s sense of justice.’

Later, as a clinic supervisor himself, Ross learned from Marg ‘the importance of empathy as a lawyer and mentor and of the power of experiential learning’.

For many contributors, Marg’s influence extended well beyond teaching technique or curriculum design. Her work shaped how lawyers understood responsibility, fairness, and the role of the profession itself.

Working alongside Marg on the South Australian Government’s Legal Needs Assessment in 2023–24, lawyer and academic Dr Mark Giancaspro observed firsthand her deep commitment to justice: ‘She consistently pushed us to reach every corner of the state, to listen carefully, and to include voices often overlooked. This shaped not just the project’s findings but how I personally approach fairness, consultation, and evidence in my own practice’.

Similarly, barrister Marissa Mackie, who served as President of the Law Society of South Australia in 2025, reflected on first meeting Marg in 2008 while undertaking Community Legal Practice:

Marg’s impact on students, the profession and legal practice more generally has been profound. She has gone above and beyond in advocating for greater access to justice and improving the culture in the legal profession … Thank you Marg for encouraging me and countless others over the years and always making the time for a chat.

Running through these reflections is a strong sense that Marg taught students and colleagues, and saw possibility in them, often before they saw it in themselves. Contributors repeatedly returned to her humour, humility, and warmth. 

Associate Professor Alex Wawryk reflects on the difficulty of identifying any single quality that explains Marg’s influence: ‘Marg is generous, humble, passionate, empathetic, extremely knowledgeable, and very, very funny, with a sometimes dry and biting wit. She has an innate sense of justice and always acts with integrity.’

Alex adds: ‘To me, her care for students is a lodestar. But most of all, in the midst of everything, life is better because she just makes me laugh.’

Dr Ross Savvas similarly reflects on Marg’s determination to keep people connected to teaching, research, and pro bono work: ‘Marg can see the strengths of people and uses her persuasive and resolution skills to ensure that those who co1ntribute to learning, research and the pro bono sector can continue to flourish and not be lost to the legal and teaching professions.’

Yet alongside her contribution to law, mediation, and access to justice, contributors reflected on Marg’s curiosity about the broader world and her infectious enthusiasm for learning itself. Former student Finn McIntyre recalled travelling with Marg to Port Lincoln to conduct legal interviews:

Marg stopped the car more than 5 times to collect pieces of plants or to look at animals. The last time I saw her, we spent the day working with researchers to catch and tag endangered lizards. She has helped me to realise that while our legal work is important, we must not forget about the world that we live in.

Read together, these reflections show that Marg’s legacy extends far beyond the programs, clinics, and initiatives she helped build. Her greatest impact lives in the students, practitioners, and colleagues shaped by her empathy, generosity, humour, and commitment to experiential learning. Across classrooms, clinics, courtrooms, and communities, those qualities continue to ripple outward— perhaps the clearest reflection of a career grounded not simply in changing institutions, but in changing the people within them.

Should Pregnant Women Be Excluded from Mediation? Questions We Need to Ask

By Dr Samantha Hardy
This article has been republished with permission. The original publication can be found at The Conflict Management Academy.

A colleague recently asked me whether I was familiar with any research on the risks associated with mediating with a heavily pregnant woman. The woman in question was in conflict with her ex-partner, the father of her unborn child, and my colleague wanted to know whether there were particular considerations they should be thinking about.

What struck me most was what came next: the mediator mentioned that their previous workplace had a policy not to mediate with women in their third trimester.

I found this troubling. And the more I thought about it, the more questions it raised about how we approach vulnerability, autonomy, and risk in mediation practice.

What Problem Are We Actually Trying to Solve?

When an organisation creates a blanket policy excluding pregnant women from mediation after a certain point, what is the underlying concern? This matters, because different concerns would lead to very different responses.

Is the worry that the stress of mediation might harm the woman? That it might harm the unborn child? That the woman might go into labour during a session? That pregnancy affects her capacity to make sound decisions? Or is it simply an administrative convenience, avoiding the unpredictability of late pregnancy?

Each of these concerns, if unpacked, reveals different assumptions about pregnant women, about mediation, and about the role mediators should play in making decisions for parties.

The Capacity Question

Let me be direct: pregnancy does not affect a woman’s capacity to make decisions. If our concern about mediating with pregnant women relates to their ability to think clearly, negotiate effectively, or understand the implications of agreements, we are on extremely shaky ground.

Pregnant women run companies, argue cases in court, perform surgery, and make countless consequential decisions every day. The suggestion that pregnancy somehow impairs decision-making capacity is not only unsupported by evidence but carries uncomfortable echoes of historical attitudes that treated pregnancy as a kind of temporary incapacity.

If a particular woman, pregnant or otherwise, lacks capacity to participate meaningfully in mediation, that should be assessed individually based on observable factors, not assumed based on her pregnancy status.

The Stress and Harm Question

Perhaps the concern is more specific: not about capacity, but about whether the stress of mediation might cause harm to the pregnant woman or her baby.

There is certainly research on prenatal stress. Studies have shown associations between maternal stress, anxiety, and depression during pregnancy and various outcomes for children, including emotional and behavioural difficulties. The mechanisms are complex, involving cortisol, the hypothalamic-pituitary-adrenal axis, and placental function.

However, this research raises more questions than it answers in the mediation context.

First, researchers distinguish between different types and intensities of stress. Chronic, severe stress appears more problematic than acute, moderate stress. Some research even suggests that mild to moderate stress may be beneficial for foetal development. The stress of a mediation session, while certainly real, is not equivalent to living in a war zone or experiencing ongoing family violence.

Second, and crucially, we need to ask: compared to what? If a pregnant woman is in conflict with her ex-partner about arrangements for their child, that conflict exists whether or not she participates in mediation. Indeed, the stress of unresolved conflict, of uncertainty, of preparing for litigation, or of simply having no process to address her concerns might well exceed the stress of participating in a structured conversation with a skilled mediator.

Third, if stress during pregnancy is our concern, why single out mediation? Pregnant women routinely engage in activities that are stressful: job interviews, examinations, difficult family conversations, moving house. We do not require medical clearance for these. Why would mediation be different?

The Medical Approval Question

My colleague and I discussed whether a pregnant woman should need medical approval before participating in mediation. The more I considered this, the more uncomfortable I became.

What exactly would we be asking a doctor to certify? That the woman is healthy enough to sit in a room and have a conversation? That her pregnancy is progressing normally? That she will not go into labour in the next few hours?

Doctors are not experts in mediation. They cannot assess whether a particular dispute is likely to be emotionally intense, how skilled the mediator is at managing difficult conversations, or how the woman herself experiences conflict. They can confirm that a pregnancy is progressing normally, but they cannot predict how any individual woman will respond to a challenging discussion.

More fundamentally, requiring medical approval before a woman can participate in a dispute resolution process positions her as someone who cannot make decisions about her own participation. It treats pregnancy as a medical condition that requires gatekeeping, rather than as a normal human experience. It is, frankly, patronising.

If we would not require medical approval for a pregnant woman to attend a job interview, negotiate a contract, or have a difficult conversation with a family member, why would we require it for mediation?

The “Going Into Labour” Concern

Perhaps the most practical concern is simply that a woman in late pregnancy might go into labour during a mediation session. This would certainly be disruptive and would require ending the session.

But is this a reason to exclude women from mediation entirely, or simply a reason to be prepared? Labour, particularly for first-time mothers, typically begins gradually. A woman who begins experiencing contractions can usually recognise what is happening and indicate that she needs to stop.

We would not exclude someone from mediation because they might have a medical emergency. We would simply respond appropriately if one occurred. Why should the possibility of labour be treated differently?

Moreover, the alternative is not risk-free. Delaying mediation until after the birth means delaying resolution of issues that may be pressing. It means the child is born into an unresolved conflict. It may mean the woman is trying to mediate while caring for a newborn, sleep-deprived and dealing with the physical recovery from childbirth. Is that preferable?

Timing: Before or After Birth?

This raises a broader question about timing that deserves more attention than it typically receives. Is it better to mediate while a woman is pregnant, or to wait until after the baby arrives?

Mediating before birth allows parties to reach agreements before the child arrives, potentially reducing stress and conflict during the newborn period. The woman can participate when she is not simultaneously caring for an infant. Issues can be addressed before they become entangled with the realities of new parenthood.

Mediating after birth means the child is a reality, not an abstraction. Parties can discuss actual arrangements rather than hypothetical ones. The mother’s circumstances, including her physical recovery and the practicalities of caring for the specific child, are known rather than predicted.

There are arguments for both approaches, and the best timing will depend on the specific circumstances. What seems problematic is making this decision for the woman by excluding her from participation during pregnancy.

The Mediator’s Role

All of this brings us back to fundamental questions about the mediator’s role. How much should we be protecting parties from processes they have chosen to engage in? When does appropriate concern for wellbeing become inappropriate paternalism?

Mediators regularly work with parties who are experiencing significant stress: people going through relationship breakdown, workplace conflict, family disputes over estates. We do not typically exclude people from mediation because they are going through difficult times. Instead, we adapt our practice: we take breaks, we check in on how people are doing, we adjust our pace, we offer to continue on another day if needed.

Could we not extend the same approach to pregnant women? Could we not simply have a conversation at the start about how she is feeling, whether there are any adjustments that would help, and what she would like to do if she becomes tired or unwell during the session?

This would treat pregnant women as capable adults who can make decisions about their own participation, while acknowledging that their circumstances may require some flexibility.

What I Would Like to See

I am not aware of any research that specifically examines the safety of mediation for pregnant women. This seems like a gap worth filling. In the meantime, I would like to see our profession engage more thoughtfully with these questions rather than defaulting to blanket policies that may do more harm than good.

I would like to see us distinguish between genuine concerns about wellbeing and unexamined assumptions about pregnancy and capacity.

I would like to see us trust women to make decisions about their own participation, while offering the flexibility and support that any party in challenging circumstances might need.

And I would like to see us ask ourselves honestly: whose interests are really being served when we exclude pregnant women from mediation? The woman’s? The baby’s? Or perhaps our own discomfort with uncertainty and difference?

These are questions, not answers. I am genuinely interested in what others in the mediation community think about this. Have you mediated with pregnant parties? Have you encountered policies like the one my colleague described? What considerations have guided your practice?

This is a conversation we should be having.
