The recent copyright case of Hamlan Homes Pty Ltd trading as Hamlan Homes and Geelong Homes v Levonix Homes Pty Ltd (No 3) [2025] FedCFamC2G 565 (Hamlan v Levonix)involved a dispute between Hamlan Homes Pty Ltd 006 313 015 (Hamlan) and Levonix Homes Pty Ltd ACN 168 777 384 (Levonix) that provides insight into preservation of “meta data” in civil litigation.

Hamlan v Levonix involved two (2) key issues, including:

  • the request for reproduction of unredacted documents; and
  • the request for the respondents to re-produce documents in their “native format”.

The first issue of requesting reproduction of unredacted documentswas considered by Manousaridis J and it was held that the documents were not directly relevant to any of the issues in dispute, so they did not have to be disclosed.  That left only the second issue of re-producing documents in their native format.

Re-producing documents in Native format

Levonix engaged an e-discovery provider, NuixDiscover (formerly Ringtail) (Nuix), to process and convert the original documents into stamped PDFs.  The stamped documents were listed in a table and provided in PDF format containing only basic metadata, such as title, document type, and attachments.[1]

Hamlan’s Solicitors subsequently requested the document list in a native Excel format, along with load files that would allow them to upload the documents to their own Nuix e-discovery software.[2]

Once this was provided to Hamlan’s solicitors, on loading the documents onto their own Nuix software, several issues were uncovered including:[3]

  • redactions without clear justification;
  • incomplete sets of documents;
  • incomplete document families;
  • documents that were non-searchable; and
  • a lack of host identifiers to group document families together in the database.

Following this, Hamlan’s Solicitors made another request, this time that all documents be reproduced in their native format, including all metadata.[4]  Counsel for Levonix argued that this would be unreasonable and create an administrative burden.[5]

Court’s ruling and reasoning

The argument by Levonix’ counsel was rejected by Manousaridis J, who ordered the documents to be reproduced in their “native format”.

In making the decision, Manousaridis J considered the definition of a “document” and the nature of electronically stored information.  It was noted that meta data is recognised as an integral part of a “document“, meaning that the metadata is just as discoverable as the document itself.  Manousaridis J concluded that producing a native file would be the most effective way to produce the its corresponding metadata.

Additionally, Manousaridis J distinguished between a “Native Format Electronic Document” and a “Derivative Electronic Document”, with the derivative format in this case referring to the converted stamped PDFs.  Manousaridis J flagged that converting files into a derivative format often results in the loss of important information embedded in the native document, such as metadata, comments, and changes in a document.

Notes about how the PDF conversion process removes meta data

When native format documents are converted to PDFs, key meta data is stripped or lost, including:

  1. application meta data (author, creation/modification dates, comments, tracked changes);
  2. email metadata (headers, send/receive times, folder paths, message IDs);
  3. file system metadata (original file paths, timestamps, source location);
  4. document relationships (email and attachments) and parent-child links; and
  5. searchability (if documents are rendered as image-based PDFs without OCR).

As a result, care needs to be taken when discovering PDFs because they can be incomplete representations and not contain the required meta data.

Implications of Hamlan v Levonix

The decision in Hamlan v Levonix is authority for the proposition that parties to legal proceedings must produce all documents in discovery in Federal Court proceedings in their native format.  This decision whilst nothing knew, reinforces the importance of preserving and providing electronically stored information in a way that maintains its’ integrity, including all embedded meta data.
