Final answer:
A restricted card can be issued in situations involving restrictive practices, such as price fixing or abusing dominant market position to limit competition.
Step-by-step explanation:
A restricted card can be issued in situations involving restrictive practices, which are actions taken by firms to limit competition in the market. One such situation is when a firm enters into an agreement with other firms to fix prices or allocate customers for their products or services.
For example, if several airlines agree to set the same prices for flights on a specific route, it would be considered a restrictive practice. Another situation is when a firm abuses its dominant position in the market to prevent or restrict competition.
This can include practices such as predatory pricing or refusal to supply competitors with essential resources.
