Background
Jackson Way owned most of lands burdened by a 1947 restrictive covenant intended to benefit adjoining retained lands, including Priorsland House. Part of Jackson Way’s lands was compulsorily acquired for the M50. In a 2003 property arbitration, compensation was assessed on the basis that Jackson Way had an unencumbered title, but Dún Laoghaire–Rathdown County Council later declined to pay after title documents showed the covenant remained registered.
In separate litigation, the Court of Appeal held in 2023 that the covenant remained valid and benefited the Smith lands. Mrs Smith had also made a statutory compensation claim against the council for impairment or extinguishment of her covenant rights arising from the motorway works. Jackson Way sought to restrain that arbitration and to join the council as a notice party, contending that any award to Mrs Smith could prejudice its effort to enforce the 2003 award.
The Court’s Holding
Nolan J refused both the interlocutory injunction and the joinder application. The proposed injunction was not supported by the substantive relief pleaded: Jackson Way’s claim sought declarations and relief concerning discharge or modification of the covenant, but did not seek to restrain Mrs Smith from pursuing her statutory compensation claim.
The Court also found Jackson Way’s claimed prejudice speculative. An award in Mrs Smith’s arbitration would determine compensation for her particular interest; it would not determine Jackson Way’s entitlement under the 2003 award or alter the Court of Appeal’s ruling that the covenant bound the acquired land. Jackson Way could not use negotiating-damages authorities, including Wrotham Park and Morris-Garner, to create a right to compel release of Mrs Smith’s property interest. The balance of justice favoured allowing her long-delayed statutory claim to proceed.
Key Takeaways
- An interlocutory injunction must be ancillary to a pleaded substantive cause of action.
- Speculation that a separate arbitration award may later be relied on by a third party is not sufficient prejudice to justify restraining that arbitration.
- Negotiating damages do not create a free-standing power to compel release of a restrictive covenant or override the beneficiary’s property rights.
Why It Matters
The decision underscores the limits on using interlocutory relief to halt a separate statutory compensation process. A party seeking such relief must identify a pleaded legal basis and a concrete risk of injustice, rather than use an injunction to improve its position in related litigation or negotiations.
It also confirms that section 50 of the Land and Conveyancing Law Reform Act 2009 supplies the statutory route for discharge or modification of restrictive covenants; an asserted inherent or common-law jurisdiction cannot duplicate that scheme.
