Learning objectives
By the end of the lesson, learners should be able to:
- distinguish an observed fact from an interpretation;
- identify the governing body, competition, and season behind a rule;
- turn rule wording into conditions that can be tested;
- acknowledge missing evidence or a genuine judgement call; and
- write a concise ruling supported by an official source.
Map the rulebook before searching it
Most organised sports answer the same broad types of question, even when the terminology and enforcement are different.
Who and where?
Participants, positions, substitutions, playing area, equipment, and eligibility.
When is play live?
Starts, restarts, periods, timekeeping, dead-ball states, and interruptions.
How is success measured?
Points, goals, runs, sets, laps, classification, ties, and winning conditions.
What is not allowed?
Fouls, faults, interference, unsafe acts, procedural breaches, and unfair advantage.
What follows?
Possession changes, restarts, base awards, cards, time penalties, disqualification, or no action.
Who decides?
Officials’ duties, judgement thresholds, reviews, appeals, protests, and final authority.
Build a ruling someone else can audit
- 1
Name the rule set
Record the sport, governing body, competition or level, and season. “The football rules” is not precise enough when competition variations matter.
- 2
Describe only what is visible
Write a neutral sequence: who moved, what touched what, where it happened, and when. Avoid labels such as “foul,” “catch,” or “travel” until the rule has been applied.
- 3
State what must be decided
Turn the argument into one focused question. For example: “Was the runner forced to advance when the base was touched?”
- 4
Find the official source
Use the governing body’s current rulebook, regulations, or official interpretation. Record the rule number and link, not only a search-result summary.
- 5
Test every condition
Break the rule into a checklist. Mark each condition yes, no, or unknown. An unknown fact may mean the clip cannot support a confident ruling.
- 6
Write the ruling and limit
Give the decision, the decisive fact, and the consequence. If the rule leaves judgement to the official, say so rather than pretending the answer is automatic.
From a baseball clip to a checkable ruling
“The runner was out because the fielder beat them to third.”
Only second base was occupied. The batter hit a ground ball. The runner moved toward third. A fielder holding the ball touched third first, without tagging the runner.
Did the batter becoming a runner remove this runner’s right to second? No: first base was empty, so there was no force chain from first to second to third.
The runner is not out merely because third was touched. An unforced runner must be tagged while off a base. The decisive fact is that the runner was not forced to third.
Learner sheet: investigate a disputed call
Choose one match incident, clip, photograph sequence, or written scenario. Complete every stage before deciding whether the official was right.
1. Identify the rule set
2. Record the observable facts
Write the sequence without using a decision word such as foul, fault, out, catch, handball, travel, or interference.
3. Write the decision question
Ask one question that the relevant rule can answer.
4. Find the official rule
Paraphrase the rule in one or two sentences:
5. Test the conditions
| Condition the rule requires | Yes | No | Unknown | Evidence |
|---|---|---|---|---|
| □ | □ | □ | ||
| □ | □ | □ | ||
| □ | □ | □ | ||
| □ | □ | □ |
6. Give the ruling
Final explanation
Under [rule set and rule number], the decision should be [ruling] because [decisive fact applied to rule]. The result is [consequence]. [State any uncertainty or competition variation.]
A five-point ruling check
- Rule set: governing body, level, and date are specific.
- Facts: the sequence is neutral and contains the details the rule tests.
- Source: the learner uses a current official rule or interpretation.
- Reasoning: every relevant condition is applied, including exceptions.
- Communication: the ruling, decisive fact, consequence, and uncertainty are clear.
Start with the governing body
Search the official site for the current rules, regulations, interpretations, or competition handbook. These examples show the kind of first-party source learners should look for.
- IFAB Laws of the GameFootball’s official laws and current changes.
- MLB Official Baseball RulesDefinitions, playing rules, appeals, and enforcement for MLB’s code.
- FIBA Official Basketball RulesRules, interpretations, and equipment guidance for FIBA basketball.
- ITF Rules and RegulationsThe official starting point for tennis rules and duties of officials.
