🎙️ Insight Over Information: Justine Campbell at National Grid on Context, Integrity and Leading at Scale
Justine Campbell, Chief Legal Officer at National Grid, joins Scott Brown to share grounded leadership insights from operating at the centre of a complex, global energy business.
In this episode of Lessons I Learned in Law, Justine reflects on what it truly means to influence at senior level in-house. She explains why the most effective lawyers focus on delivering insight rather than just information, understanding business context, stakeholder priorities and the pace at which decisions need to be made.
She also explores how strong legal leadership is built through assembling diverse, high-performing teams. From creating space for constructive challenge to investing in trusted peer networks outside the organisation, Justine shares candid reflections on how perspective shapes better judgement.
Her final lesson centres on recognising the responsibility that comes with senior legal roles. Whether advising boards, managing crises or shaping organisational integrity, she highlights why lawyers must balance technical excellence with emotional intelligence and resilience. Listeners also hear personal insights, including her early ambitions outside law and the importance she places on maintaining curiosity throughout her career.
