use Illuminate\Foundation\Http\FormRequest;
use App\Rules\DepartementManagerRule;

class StoreRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'title' => 'required|min:5|max:200',
            'body' => 'required',
            'department_manager' => [
                'required',
                new DepartementManagerRule,
             ]
        ];

php artisan make:rule DepartementManagerRule

<?php

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class DepartementManagerRule implements Rule

    /**

     *
     * @return void
     */
    public function __construct()
    {
        //

    /**
     * Determine if the validation rule passes.
     *
     * @param  string  $attribute
     * @param  mixed  $value
     * @return bool
     */
    public function passes($attribute, $value)
    {
        return (empty($value) || empty(\Auth::user()->id) || $value == \Auth::user()->id ? false : true);
    }

    /**
     * Get the validation error message.
     *
