Employment
In the High Court, Simon regularly acts in fraud, business diversion and employee competition disputes. He is described in the directories as a “go-to silk for non-compete disputes” and frequently acts (for both sides) in confidential information, restrictive covenant, team move and business diversion cases (in both the employment and the LLP settings). Other related areas of expertise include actions for injunctions to restrain or curtail domestic disciplinary proceedings (particularly in the NHS context) and the control of repeated litigation by disgruntled employees.
Recent reported and/or important cases include Red Bull -v- Fallows [2021] EWHC 3502 (QB) (disclosure necessary to test restraint of trade claims in the garden leave context); Capita -v- Darch {2017] IRLR 718 (threshold for interim injunctive relief in team move disputes); Samara –v- MBI Partners [2016] EWHC 441 (QB) (abuse of process arising out of recidivist litigation); Dorma UK Ltd –v- Batemen [2015] EWHC 4142 (QB) [2016] IRLR 616 (springboard relief arising out of an alleged team move); Miller –v- Gardiner & Ors [2015] EWHC 1712 (Ch) & [2015] EWHC 288 (Ch) (extended CRO against litigant repeatedly bringing misconceived claims); Thomson Ecology –v- APEM [2014] IRLR 184 (summary judgment and disclosure orders in team move cases); CEF Holdings -v- Mundey & Ors [2012] FSR 35 (the limits of springboard relief and the obligations of a party moving the court without notice); BGC –v- Rees & Tullett Prebon [2011] EWHC 2009 (QB) (Tullett did not procure Rees to breach his contract of employment with BGC when recruiting him); Capital for Enterprise -v- Malik & Ors [2010] EWHC 343 (Ch) (disclosure obligations and freezing injunctions); Bezant –v- Rausing & Ors [2007] EWHC 1118 (QB) (it was an abuse of process for a claimant, after his claims under employment law had failed, to seek to invoke the law of tort against directors and other professionals associated with his employment/dismissal, to seek to recover his alleged losses).
On the statutory front, Simon is noted in the directories for his strength “in structuring his arguments in a way that finds favour with the Employment Tribunal, and in making persuasive submissions”. He frequently acts for banks and financial institutions in high value claims and continues to handle a large number of whistle-blowing disputes, arising particularly in the financial services sector. He also advises on contentious and no-contentious TUPE issues, particularly in respect of outsourcing and change of contractor disputes and on the TUPE implications of commercial transactions. He recently acted for the successful party in arguing that variations to personal terms agreed by employee/directors in anticipation of a transfer were void under TUPE. He has acted for a number of NHS bodies following the outsourcing of care to persons with learning disabilities, and successfully defended a firm of solicitors against a claim that it had inherited TUPE liabilities for the employees of one of its competitors.
Recent reported and/or important cases include: Ferguson -v- Astrea [2020] IRLR 550 (the first case to consider whether beneficial variations were void under TUPE and the application of the EU abuse of rights principle to TUPE claims); Sattar -v- Citibank [2020] IRLR 104 (procedural fairness in dismissal and disability contexts following the dismissal of Citi’s Global Head of Treasury); Allsop –v- Christiani & Nielsen Ltd (in Administration) [2012] UKEAT/0241/11/JOJ (limitation and jurisdiction in Wages Act claims); Royal Cornwall Hospital Trust –v- Watkinson [2011] Med LR 636 (whistleblowing in an NHS trust); Ward Hadaway –v- Love & Ors [2010] UKEAT/0471/09/SM (the winning of a contract to provide legal services to the NMC did not constitute a service provision change within the meaning of TUPE 2006, and the successful tenderer did not assume liability for the dedicated team of lawyers retained by his predecessor); New ISG –v- Vernon & Ors [2008] ICR 319 (a purposive construction should be given to reg 4(7) of TUPE 2006, so as to accord with the fundamental freedom of the employee to choose who he works for, and to permit and recognise the effectiveness of a post transfer objection where the employee does not know of the identity of the transferee or of his right to object pre transfer. In consequence, the transferee could not enforce post termination restrictive covenants against ‘objecting’ employees); Croke –v- Hydro [2007] ICR 1303 (an individual providing services through his own limited company to an end user via an employment agency was a worker for the purposes of the whistle-blowing provisions); Perkin –v- St George’s NHS Trust [2006] ICR 617 (awkward personality as the justification for the dismissal of a self-proclaimed whistleblower).
