Rodrigues v Sokal

The Party Wall etc Act 1996 provides an exhaustive procedure for disputes falling within its scope. A building owner cannot rely on statutory protection for unauthorised works until the statutory procedure has been invoked and consent or authority obtained. Later authority may abate common-law rights from the date of that authority, but does not necessarily retrospectively authorise earlier nuisance.

An award under section 10(16) is conclusive on the matters determined. Where the award makes findings concerning works carried out both before and after the procedure was invoked, those findings cannot be reopened in other proceedings on different evidence, subject to any distinct issue such as temporary disruption before the procedure commenced.

The claimants owned one half of a semi-detached property. The defendant owned the other half and carried out substantial conversion and construction works. The claimants alleged that the works threatened the structural integrity of their property and caused actual damage.

A party wall surveyor, Mr North, made an award under the Party Wall etc Act 1996. He found that the defendant had not caused damage or instability to the party wall and that adequate ties had been installed. The defendant sought determination that specified claims in the claimants’ Scott Schedule could no longer be pursued because the award was conclusive under section 10(16).

The central issue was whether the award conclusively determined matters relating to works carried out before the party wall procedure was invoked.

1. The court found for the defendant on the preliminary issue. The claimants could not pursue the specified claims concerning threatened structural integrity or alleged actual damage.

2. The statutory scheme under the Party Wall etc Act 1996 supersedes common-law rights in relation to matters within the Act. Until the procedure is invoked and consent or statutory authority is obtained, a building owner cannot rely on a statutory defence for works undertaken without complying with the Act. Where works are subsequently authorised, the adjoining owner’s common-law rights are abated from the date of the subsequent consent or successful invocation of the statutory procedure. This principle was derived from Louis v Sadiq [1997] 1 EGLR 136.

3. The court distinguished Louis v Sadiq because the works in that case could never have been authorised retrospectively, whereas the works in the present case had been approved.

4. Section 10(16) made Mr North’s award conclusive in relation to the findings it contained. Those findings covered works carried out both before and after 15 May 2004 because they addressed the works as a whole and matters common to both periods. Section 10(17) prevented the claimants from reopening the same issues by relying on other evidence.

5. The court rejected the argument that Mr North’s findings were tentative. Even if the claimants’ expert report were considered, it was rejected insofar as it conflicted with the award. The court noted that a separate issue might arise concerning temporary disruption occurring between creation of a nuisance and commencement of the statutory procedure.
