Final answer:
The act of upskirting became a criminal offence in the United Kingdom with the Voyeurism (Offences) Act 2019.
Step-by-step explanation:
The act of upskirting, which involves taking unauthorized photographs or videos under a person's clothing without their consent, became a criminal offence in different jurisdictions at different times.
In the United Kingdom, upskirting was initially not explicitly covered by law, leading to a campaign for its criminalization.
The Voyeurism (Offences) Act 2019 was finally passed in the UK on February 12, 2019, making upskirting a criminal offence punishable by imprisonment.
