The primary source
Rules are published in the official gazette; whether a change actually happened is seen there. Secondary sources — bulletins, news, an adviser's note — are faster but may be incomplete or interpreted. The right arrangement: hear it from a secondary source and verify it in the primary one.
Building the filter
- the names of the laws and regulations in the register,
- the rules issued by the relevant ministries and authorities,
- subject headings specific to your activity,
- items updated every year: fine amounts, the hazard class list, threshold values.
What makes it sustainable
If tracking rests on one person's voluntary habit, it stops when they go on leave. So the owner, the frequency and where it is recorded are written down, and there is somewhere that shows when tracking did not happen.
Between publication and effect
A rule that takes effect after publication leaves that interval for preparation. The tracking record keeps the two dates apart; otherwise you get either premature panic or lateness.
More than one source
Tracking tied to a single source misses whatever that source misses. Watching the primary source together with at least one secondary one makes omissions measurable.
