Final answer:
In Shakespeare's 'A Midsummer Night's Dream', Lysander accuses Demetrius of being fickle and inconstant in love, initially courting Helena before shifting his affection to Hermia.
Step-by-step explanation:
Demetrius is not accused by Lysander in a legal sense, rather he is accused in a personal dispute within William Shakespeare's play, "A Midsummer Night's Dream." In the play, Lysander accuses Demetrius of being inconstant and fickle in love, as Demetrius first courted Helena but then shifted his affections to Hermia, causing emotional turmoil and conflict among the characters.
Furthermore, Lysander suggests that Demetrius has treated Helena unfairly, disregarding her love and devotion. These interpersonal accusations reflect the complex relationships and themes of love and fidelity in Shakespeare's comedy.
