Building a Cross-Country Regulatory Comparison
Compare regulatory questions across countries with consistent definitions, dated sources and explicit gaps, using a jurisdiction comparison matrix.
A cross-country regulatory comparison is a controlled record of what is being compared, at which stage of a rule's life each item stands, and on what documentary basis the statement rests. Its purpose is not to collect statutes but to let a reader distinguish a settled requirement from a proposal, a verified text from a summary, and a confirmed date from an assumption. Comparisons fail less often through missing jurisdictions than through mismatched units and unmarked status.
Fix the unit of comparison before reading any text
Three elements determine whether two rows belong in the same comparison: the activity, the actor on whom the obligation falls, and the trigger that brings the rule into play. A licence that attaches to a firm in one jurisdiction and to an individual adviser in another cannot be compared until the matrix separates the firm row from the individual row. The content may be accurate in both cases; the comparison is still invalid because the subjects differ.
Write the question before the answer, in a form that can be resolved. "Does a firm need authorisation to give written investment advice to retail clients?" is answerable. "What are the licensing requirements?" invites a summary that cannot be checked against a source.
Scope also needs a stated edge. Record which instruments were searched, at which level of government, in which languages, and which were excluded. A comparison of national statutes that omits binding subnational rules is not wrong, but it must say so.
Four rule statuses that are not interchangeable
The commonest defect in comparative work is a status error. Two jurisdictions appear aligned because both have "adopted" a rule, when only one has commenced it.
| Status | What it establishes | What it does not establish |
|---|---|---|
| Proposal | A published draft, consultation paper or announced intention exists | Any current obligation; the text may change or be withdrawn |
| Adoption | The instrument has been made or enacted in the form cited | That obligations are operative |
| Commencement | The rule applies from a stated date, possibly in stages | That earlier arrangements are unaffected; transitional provisions may govern them |
| Guidance | How an authority says it will read or apply the text | That the interpretation is binding, or that it will survive challenge |
Adoption and commencement are frequently separated by months in the same jurisdiction, and the gap is where most mislabelled rows originate. Guidance requires its own treatment: some regulators issue it with statutory force, others state expressly that it is not binding. Record which, rather than assuming either.
Transitional provisions deserve a separate check when the activity is already being carried out. The question covers both when the rule starts and which version applies to an arrangement that predates it.
A working matrix
The format below is a suggested working method, not a validated instrument or an institutional requirement. Adapt the columns to the decision the comparison is meant to support.
| Column | Purpose | Entry rule |
|---|---|---|
| Activity | Defines what is being regulated | Use the same verb and object across jurisdictions; note where a term has no exact equivalent |
| Actor | Identifies who bears the obligation | Firm, individual, officer, third party; keep separate rows |
| Question | States the point to be resolved | Answerable form; one question per row |
| Rule status | Places the item at proposal, adoption, commencement or guidance | Cite the instrument that fixes the status |
| Source and version | Anchors the claim | Publisher, title, section, document version, access date |
| Confirmed effective date | Separates operative from pending | Only from the commencement instrument or text; otherwise unknown |
| Interpretation limit | Records what the source does not settle | Ambiguity, undefined terms, non-binding status, pending litigation |
| Local question | Names what a qualified adviser must resolve | Specific, scoped, answerable in writing |
Two disciplines keep the matrix honest. First, record the extracted fact and the analysis note separately, so a later reader can see where observation ends and judgement begins. Second, treat "unknown" as a value rather than a gap to be filled by inference. Distinguish three states that are often collapsed: not applicable, with the reason; not found in the sources searched, with the list of sources; and not yet checked. A missing effective date is not a date.
Keeping the source basis when a document changes
Guidance pages and draft texts are amended without notice. When a cited page changes mid-draft, retain the previous basis, record the date on which it was retrieved, and note what needs rechecking rather than silently substituting the new text. The United Kingdom's Aqua Book, published by HM Treasury, sets expectations for the analysis and quality assurance of evidence used to support policy decisions within the UK public sector (HM Treasury, The Aqua Book). The practical implication for a comparison is a version log: every row carries the version it was drafted against, and every revision carries a reason.
A fictional worked example
The following illustration is fictional. It describes two unnamed jurisdictions with different licensing definitions and does not reflect current law anywhere. Versions, dates and outcomes are invented for the example only.
The activity: providing a one-off written opinion on a financial product to a retail client.
| Row | Actor and question | Status | Source and version | What remains open |
|---|---|---|---|---|
| 1 | Firm: must it hold a licence to give written advice? | Adoption; commencement instrument not located | Draft Bill 14, version 3, section 9, accessed at a fictional drafting date | Whether "advice" covers a single written opinion; the explanatory note refers to oral and written forms without defining either |
| 2 | Individual: must the adviser be registered? | In force | Regulator guidance, paragraph 4.2, version 2 | Guidance states it is non-binding; whether registration attaches to the individual or to the firm's approval of the individual is unresolved |
| 3 | Firm: is there a firm-level licence in the second jurisdiction? | Not found in the sources searched | Licensing Act, schedule of licensed activities, version as cited | A negative finding needs confirmation from local counsel before it is recorded as an absence |
| 4 | Individual: is there an individual-level registration in the second jurisdiction? | Proposal only | Consultation paper, version 1 | No adopted text; the row must not be compared with row 2 as though both were operative |
The example shows the two failures the matrix is designed to prevent. Rows 1 and 3 describe firm obligations in different statuses and cannot be read as a comparison of stringency. Rows 2 and 4 describe the same actor but sit at different stages of the rule's life; a reader who compares them without the status column will conclude that one jurisdiction is stricter when the difference is procedural.
When local advice becomes necessary
A general comparison can be assembled from published sources. Certain conditions, however, transfer the question to a qualified adviser in the jurisdiction concerned. These are conditions rather than universal rules; each depends on the purpose of the comparison and the reader's tolerance for residual uncertainty.
- The operative text is in a language the researcher does not read at a professional level, and the available translation is unofficial.
- The obligation sits in subnational legislation, and the activity crosses internal jurisdictional boundaries.
- The guidance carries no statutory force but is reported to reflect enforcement practice.
- Commencement depends on an instrument not yet published, and the client's decision turns on timing.
- The activity is professionally licensed, so a second regulator's rules apply alongside the general regime.
- Transitional provisions determine which version governs an existing arrangement.
- The characterisation of the activity is contested: advice against information, arrangement against execution, or a regulated product against an unregulated one.
Scope the instruction to the row rather than the project. Give the adviser the activity, actor and question as recorded, ask for a written answer with the source and version relied on, and ask whether the answer may be recorded in the matrix. An answer that cannot be attributed to a text is a data point about practice, not about the rule.
Reviewing the comparison before circulation
A second reader should test comparability rather than legal accuracy. The questions are whether every row uses the same activity and actor definition, whether any row mixes statuses, whether each effective date traces to a commencement instrument, and whether every unresolved point appears in the interpretation limit or local question column.
Date-stamp the finished matrix and state its scope limits: instruments covered, levels of government, languages, and sources not searched. Where the comparison is a selected review of defined instruments, describe it as such; the label of systematic review implies a method and comprehensiveness that a policy matrix does not ordinarily meet.
For researchers deciding how far to take the exercise, the practical starting point is one activity and two jurisdictions, completed to eight rows with the unresolved entries left visible. That small matrix will show quickly whether the comparison can be built from published material or needs local confirmation.
