ISSUE:
Whether regulations mandating termination of employment upon pregnancy or imposing differential retirement ages constitute arbitrary or discriminatory treatment, thereby violating constitutional principles of equality?
Whether restrictions on personal choices, such as marriage within a specified period, amount to an unreasonable encroachment on individual rights or are justified by legitimate objectives?
RULE:
A regulation or policy must not result in arbitrary or unreasonable treatment; classifications must be based on intelligible differentia with a rational nexus to the objective sought to be achieved, and restrictions on rights must be proportionate and serve a legitimate public purpose.
