Industrial action: Union strike ballots not invalidated by minor breaches

In RMT v Serco Ltd t/a Serco Docklands; ASLEF v London & Birmingham Railway Ltd t/a London Midland [2011] EWCA Civ 226 CA, the Court of Appeal ruled in relation to strike ballots that the respective unions had done enough to call lawful strike action and that the High Court had been wrong to grant injunctions preventing the action from going ahead. In each case, the union had complied sufficiently with the appropriate statutory requirements to render the industrial action lawful.
