Nick Isaac’s argues de minimis works are not notifiable REALLY !!!!!!!

This blog follows on from our earlier blog

This is the second element of these two important party wall cases heard on the 16.03.20

Zaher and Oger-Zaher v Patel (2020) CLCC F20CL100 and

MacLachlan v Patel (2020) CLCC F20CL099

The two cases were before HHJ Richard James Lloyd Roberts is a Circuit Judge, deployed to the South Eastern circuit, based at Central London and Mayors and City of London County Court He was appointed as a Master of the Queen’s Bench Division in 2009 at the Royal Courts of Justice, London, UK

Excavations are de minimis claims Mr. Nicholas Isaac QC mmm well let’s just analyze that statement.

The Defendant (Mr. Patel) was building rear extensions on two separate properties these involved excavating the ground to create a 300 mm thick reinforced concrete slab that would be sitting on a series of cast in situ steel-lined driven piles.

Injunctions were obtained and at the return date hearing on the 16th March 2020 Mr. Isaac claimed that the excavation for the slabs was de minimis because the excavation only went lightly lower than the foundations of a boundary wall built on the line of junction within the ownership of Ms. MacLachlan,

Surprisingly he ignored the paving slabs, patio, and in relation to both ZaherMs. MacLachlan essentially contradicting what he promotes in his book where Mr. Isaac accepts that paving slabs, paths, paviours patios are structures, and any excavation that goes lower than these structures is notifiable under the Act.

Why on earth would Mr. Isaac argue against his own book, well that remains one of life’s great mysteries but it’s not the first time that Philip Antino has successfully caught Mr. Isaac out and quoted Mr. Isaac’s book back to him?

Indeed, in the Mohammed v Antino and Stevens case, he had the audacity to congratulate Mr. Antino before HHJ Bailey (now retired) for successfully quoting his book back at him. The arrogance of it!!!!

In any event, Philip Antino’s opinion in relation to the de minimis claim was that Mr. Isaac was simply wrong in law, for the following reasons; -

1) The Act does not recognize de minimis works, if you excavate below the structure or foundations of an adjoining owner’s property even if it is only for an inch or so, it is notifiable.

2) Excavating for Mr. Patel’s slab required breaking out and the removal of just over 7 tonnes of hardcore, earth, paving slabs, patios, stones, etc. That cannot be de minimis works.

3) It also required the pouring 7 tonnes of reinforced concrete, which cannot be considered de minimis.

4) The slab had to be designed by a structural engineer, any structure requires this level of professional design input cannot by any definition be de minimis.

5) These works were subject to building control approval and inspection, anything that requires building control inspection and approval cannot by definition be de minimis.

On any analysis of the works, it must be correct as suggested by Mr. Philip Antino’s that Mr. Isaac’s submission that these de minimis work and therefore not notifiable under the Act were simply nonsense.

The learned Judge, HHJ Roberts in addressing Mr. Isaac sated: -

“This all seems to be Alice in Wonderland”

“your submission does not attract water, let alone hold it, Mr Isaac”.

“You are clutching at straws Mr. Isaac.”

just about says it all really!!!

A very common-sense analysis of a rather bizarre and erroneous argument which cost Mr. Patel a pretty penny in Costs (£200,000).

The Judge rose to advise that he would be returning about 30 – 45 minutes which his judgment.

Mr. Isaac took his client outside then came in and made several offers to settle.

Whilst there has not been a judgment it is clear that Mr. Isaac’s case was to quote Frazer from Dad’s Army “DOOOOOMED” to failure. This was an amazing result for both David Mayall, Ashley Bean, and Philip Antino and their clients, it was also a fantastic result for the party wall community who can draw comfort that not all that Mr. Isaac suggests is correct in fact far from it.

Rather bizarrely two days after the hearing Mr. Patel then wrote to Philip Antino and tried to encourage him to act for him on his party wall matters. Philip Antino declined.

Judges Comments and Opinions regarding Dr. Antino

  • Miss Recorder Rowlands H01CL719 in Moore v Ahmed 2023

    I accept Mr Antino's (as he then was) evidence that Mr Tugby had sought instructions form Dr Ahmed as to the lien of the boundary.

  • In any industry there are always organisations that stand out from their peers and set the standards that others in their field have to aspire to achieve. First established back in 2001, APA Property Services is an organisation that certainly meets this criteria leading the way when it comes to providing construction, surveying and engineering consultancy services. They have made quite a name for themselves over the years establishing a well deserved reputation as one of the leaders in their field and if the last few years are any barometer of what the future holds then there are many successful chapters yet to be written in the APA Property Services story.

  • The party wall world is relatively small, the stage of this world contains a number of well-known players, Mr Antino is one of these well-known players and so are his owners instructing solicitor Mr Ashley Bean of Thirsk Winton

    HHJ Bailey - [2016]
  • The Claimants have a very experienced legal team comprising Mr David Mayall of lambchambers & Mr Ashley Bean of thirsK winton and their surveyro Dr. Philip Antino. The evidence in particular of the Defendant’s plans for both the Accessway and the plans and how it impacted upon the Claimants business was important information that The Defendants ahd not provided when requested.

    HHJ Freedland QC - [2021]
  • "Mr Antino is a palpable witness, Mr Antino's explanation of the unique attributes of the "Thompson Plan" greatly assisted the Court to understand the location and extent of the claimants’ boundaries” (Best & Best v Perkins & Dennis in the County Court at Luton).

    HHJ Hildyard - [2015]
  • The appeal was a preliminary hearing of two points in respect of an Award served by Mr Antino and a surveyor appointed by Mr Antino under s.10(4) on behalf of the Building Owners the Appellants. HHJ Luba QC sitting in the Central London County Court held "In my judgment the Award is valid, the use of s.10(4) was the appropriate procedure given the Building Owners refusal to appoint a surveyor. A dispute had arisen that satisfied s.10 procedures, The Award is an impressive piece of work". Schmid v Hulls and Athananasou).

    HHJ Luba QC - [2016]
  • “Mr Antino is an acknowledged expert in the field of party wall issues.”

    HHJ Murfitt QC 2013 - [2015]
  • “I have known Philip for many years as a surveyor, he is a very good surveyor, as this book shows he is a very good author and this book can only advance his reputation”

    HHJ Philip Bartle QC - [2012]
  • “In the appeal of an ex-parte Award served by Mr Antino on behalf of the respondents, in my judgment the respondent is correct. Mr Antino’s contention that it is not a matter for negotiation directly between one surveyor and the other surveyor’s client. Since I have determined that the ex-parte Award was valid the court is still able to determine the Award and under the statutory powers to modify the Award if appropriate. I am grateful to Mr Antino suggesting that I now determine the Award issue “I accept that Mr Antino’s hourly rate is not in my judgment unreasonable. It follows that the fee set out in the ex-parte Award had been properly justified and I therefore award Mr Antino’s fees”. (Bansal v Myers Romford County Court).

  • Why the Federation of Forensic and Expert Witnesses Has Selected APA Property Services Ltd for the Industry Leadership in Building Consultancy & Expert Witness Services Award 2026–2027
    Setting the Benchmark for Excellence in Construction Consultancy and Expert Evidence
    Within the increasingly complex world of construction disputes, building failures and property litigation, solicitors require far more than technical opinion. They require expert witnesses capable of interpreting highly technical construction issues, presenting independent evidence that withstands judicial scrutiny, and assisting the Court in reaching fair, balanced and technically accurate conclusions.
    It is for these reasons that the Federation of Forensic and Expert Witnesses (FFEW) has chosen APA Property Services Ltd, under the leadership of Dr Philip Antino, as the recipient of the Industry Leadership in Building Consultancy & Expert Witness Services Award 2026–2027.

    The award reflects far more than individual achievement. It recognises an organisation that has consistently demonstrated exceptional professional standards, technical excellence, innovation, legal understanding and an unwavering commitment to independent expert evidence over many years.
    Founded in 2001, APA Property Services has developed into one of the United Kingdom's most respected multidisciplinary construction consultancies, providing specialist building consultancy, expert witness services, dispute resolution, building surveying and engineering advice across both the public and private sectors. From its headquarters in Chelmsford, the practice advises clients throughout England and Wales, combining practical commercial experience with academic excellence and extensive courtroom expertise.
    A Reputation Built on Knowledge, Independence and Professional Integrity

    One of the principal reasons behind the Federation's decision is the exceptional depth of expertise demonstrated by Dr Philip Antino throughout his distinguished career.
    Unlike many construction consultants, Dr Antino combines more than four decades of practical industry experience with outstanding academic credentials. He is recognised as the first person in the world to have been awarded a PhD specifically examining the interpretation of the Party Wall etc. Act 1996 and its implications for below-ground construction, research that has contributed significantly to professional understanding within this specialist area. His academic achievements are complemented by degrees in Building Surveying, Construction Management and Research, providing a rare combination of practical experience and scholarly authority.

    However, qualifications alone do not explain APA Property Services' success.
    The Federation places considerable importance upon professional integrity, independence and the ability to assist the Courts objectively. APA has built its reputation on providing impartial, CPR Part 35-compliant expert reports that serve the interests of justice rather than the interests of the instructing party. This independence lies at the very heart of expert witness practice and remains one of the defining characteristics of the firm's work.

    Trusted Across the Construction and Legal Professions
    APA Property Services today offers one of the broadest portfolios of specialist construction consultancy services available within the expert witness sector.
    The practice regularly advises upon:
    ● Building defects and structural failures
    ● Professional negligence claims
    ● Housing disrepair
    ● Party Wall disputes
    ● Boundary disputes
    ● Landlord and tenant matters
    ● Building contract disputes
    ● Fire safety and construction issues
    ● Forensic building investigations
    ● Alternative Dispute Resolution
    ● Arbitration and adjudication
    ● Building surveying and project consultancy

    This breadth of expertise enables solicitors to instruct one highly experienced consultancy capable of addressing numerous interconnected construction issues within a single litigation matter, creating consistency, efficiency and significant cost savings for clients.
    Courtroom Experience That Inspires Confidence
    Perhaps the strongest endorsement of APA Property Services comes not from marketing literature but from the judiciary itself.

    Over many years, Dr Antino's evidence has been considered by County Courts, the High Court, the Court of Appeal, Crown Courts, Magistrates' Courts and specialist Tribunals. His expert opinions have been relied upon in complex disputes involving boundary interpretation, Party Wall legislation, professional negligence and technical construction matters.
    Published judicial comments available on APA's website illustrate the level of confidence placed in his work. Judges have referred to him as an acknowledged expert in Party Wall matters, praised the quality of his awards and recognised the assistance his technical evidence has provided in helping the Court understand complicated construction issues. These observations reinforce what many solicitors already recognise—that technically robust, independent expert evidence can significantly assist litigation by clarifying the real issues in dispute.
    Courtroom Experience That Inspires Confidence
    Why Solicitors Continue to Instruct APA Property Services
    For legal practitioners, selecting an expert witness is ultimately about confidence.
    Confidence that the expert possesses the appropriate qualifications.
    Confidence that the report will comply fully with Civil Procedure Rules.
    Confidence that technical conclusions are evidence-based.
    Confidence that the expert can withstand cross-examination.
    Confidence that complex engineering or surveying issues can be explained clearly to judges, barristers and clients.

    APA Property Services has established an enviable reputation for delivering precisely this level of confidence.
    The practice accepts instructions from claimant and defendant solicitors alike, together with appointments as Single Joint Expert where appropriate. Importantly, the firm's philosophy is not simply to prepare reports for litigation but, wherever possible, to assist parties in understanding the strengths and weaknesses of their respective positions. Early independent expert advice often enables disputes to be resolved without the significant financial and emotional cost of lengthy court proceedings, providing tangible benefits for both clients and the justice system.
    A Consultancy That Continues to Raise Standards

    The Federation does not present this award solely in recognition of past achievements.
    Instead, the Industry Leadership Award recognises organisations that continue to evolve, innovate and influence professional standards across their sector.
    APA Property Services has consistently expanded its capabilities while maintaining exceptionally high standards of technical quality, independence and client service. The practice has embraced multidisciplinary consultancy, strengthened its expert witness offering and continued investing in professional development while preserving the personal service expected by solicitors and commercial clients alike.
    These qualities distinguish genuinely outstanding consultancies from those that merely provide technical reports.

    A Well-Deserved Recognition

    The Federation has previously recognised Dr Philip Antino and APA Property Services through several prestigious awards, including the Lifetime Achievement Award and Outstanding Expert Services to Construction & Engineering Law. Rather than resting on these accomplishments, the practice has continued to enhance its reputation through sustained professional excellence, investment in research, expansion of specialist services and an unwavering commitment to independent expert evidence.
    For the Federation of Forensic and Expert Witnesses, the decision to honour APA Property Services once again reflects careful observation of the firm's continued progression and influence within both the construction and legal professions.

    In today's increasingly demanding litigation environment, solicitors require experts who combine exceptional technical knowledge with independence, clarity, credibility and courtroom experience.
    APA Property Services has demonstrated these qualities consistently for more than two decades.

    It is therefore entirely fitting that the Federation recognises Dr Philip Antino and APA Property Services Ltd with the Industry Leadership in Building Consultancy & Expert Witness Services Award 2026–2027, acknowledging an organisation that continues to set the benchmark for excellence in construction consultancy, expert witness practice and professional leadership throughout the United Kin
